Description

Technical Field

[0001] This invention belongs to, but is not limited to, the field of star-shaped keyboard communication technology, and particularly relates to a star-shaped keyboard anti-multi-source interference communication method and device that integrates Polar codes and SLB. Background Technology

[0002] Current wireless keyboard technology faces severe spectrum resource challenges, especially in the 2.4GHz public band. With the explosive growth of Wi-Fi 6, Bluetooth 5.0, and various IoT devices, spectrum congestion has become a key bottleneck restricting the performance of wireless input devices. StarFlash technology, as a new generation of short-range wireless communication standard independently developed in my country, although it has advantages in latency (<1ms) and reliability (PER<10), still faces challenges. -5 While possessing inherent advantages in this area, the Xingshan keyboard still faces challenges in practical deployments due to three typical interference scenarios: First, high-density multi-device coexistence environments, such as esports competitions where hundreds of 2.4GHz transmitters may exist simultaneously, causing traditional CSMA / CA mechanisms to fail; second, broadband electromagnetic interference in industrial environments, including periodic noise generated by devices such as frequency converters and servo motors, whose spectral characteristics highly overlap with communication signals; and third, targeted malicious interference, where external devices may launch targeted interference attacks in critical scenarios such as professional esports. Existing solutions mainly employ static frequency band avoidance or simple power enhancement strategies, resulting in spectrum utilization rates consistently below 40% and device power consumption increases by more than 30%, severely restricting the application expansion of Xingshan keyboards in mobile office, industrial control, and other scenarios. Even more serious is the lack of deep adaptation to keyboard data characteristics in traditional solutions—high-frequency letter keys and low-frequency function keys have drastically different reliability requirements, while existing systems all use a unified communication strategy, resulting in resource waste and failing to meet the extreme reliability requirements of esports-grade input devices for critical commands. This current technological situation urgently requires breakthrough innovations in physical layer coding and link layer anti-interference mechanisms.

[0003] In the published patent GB2406479A "Adaptive frequency-hopping", Toshiba Research proposed to reduce the collision probability of Bluetooth or similar 2.4GHz devices in environments with interference sources such as Wi-Fi by measuring the signal quality of each frequency-hopping channel in real time, eliminating interfering channels, and dynamically adjusting the frequency-hopping sequence. The core mechanism relies entirely on frequency domain interference assessment and channel blacklist maintenance, enabling adaptive channel selection under lightweight hardware conditions, thereby maintaining the basic availability of peripheral links. This solution, like this invention, is based on short-range peripheral communication and targets multi-source ISM interference, but its protection logic is limited to a single frequency dimension of "retaining good channels and eliminating bad channels," without introducing pattern control, error correction code reconstruction, or keypad service priority management.

[0004] However, in high-density wireless environments such as industrial and e-sports scenarios, interference exhibits complex characteristics such as broadband superposition, burst pulses, and spatial clustering. The simple frequency hopping strategy has two major drawbacks: First, as available channels are continuously marked as "bad," the frequency hopping sequence converges rapidly, leading to throughput attenuation and keystroke delay jitter. Second, the solution lacks differentiated processing for instantaneous high-power narrowband interference and continuous broadband noise floor, and does not combine Polar code dynamic coding rate, beamforming null suppression, and machine learning-driven interference type identification. Therefore, it is difficult to maintain a low error rate while ensuring efficient link utilization, leaving technical gaps in the coexistence of multi-source interference and insufficient service-level reliability. Summary of the Invention

[0005] To address the problems existing in the prior art, this invention provides a method and apparatus for anti-multi-source interference communication using a star-flash keyboard that integrates Polar codes and SLB.

[0006] This invention is implemented as follows: a star-flash keyboard anti-multi-source interference communication method integrating Polar codes and SLB algorithm, comprising:

[0007] a. Environment initialization and baseline scanning: Directional calibration is completed using a four-element cross-shaped directional antenna array and eight beam radiation templates are generated. Full bandwidth scanning of the working frequency band is performed using a spectrum analyzer to establish an electromagnetic environment fingerprint database and a key priority mapping table.

[0008] b. Real-time multi-dimensional interference perception: The phase difference measurement technology is used to obtain the angle of arrival of interference, the fast Fourier transform is used to analyze the spectrum occupancy, the instantaneous interference and continuous interference are distinguished according to the burst statistics of bit error, and the perception data is input into the pre-trained interference recognition model;

[0009] c. Intelligent decision-making and parameter optimization: The SLB intelligent load balancing algorithm dynamically configures the working mode, channel, polarization mode and Polar code related parameters according to the type of interference.

[0010] d. Adaptive transmission execution: During periods of high interference, directional beamforming and strong error correction coding are combined, and during periods of low interference, the system switches to a high-efficiency transmission mode, achieving a seamless transition through a microsecond-level switching mechanism;

[0011] e. Dynamic optimization and online learning: Periodically update the interference feature database and retrain the interference identification model in real time based on communication quality feedback.

[0012] Furthermore, in step c, differentiated strategies are adopted for different types of interference; when Wi-Fi interference is detected, a collision avoidance coding scheme is enabled and a directional beam is switched; when Bluetooth interference is detected, a dedicated communication channel is switched and error correction redundancy is improved; when unknown interference is detected, frequency hopping and redundant transmission are implemented and hierarchical protection is performed based on key priority.

[0013] Furthermore, the coding rate R of the Polar code is adaptively adjusted according to the interference intensity. Specifically, the initial coding rate is set to 0.75; the normalized interference intensity is measured and taken as a value between 0 and 1; the interference intensity is multiplied by the interference sensitivity coefficient between 1 / 2 and 1 / 8, and then the natural exponent value is taken; finally, the product of the initial coding rate and the exponent value is taken as the current coding rate.

[0014] Furthermore, when the packet error rate of the communication quality indicator exceeds the threshold TPER, parameter reconfiguration is immediately triggered. The threshold is obtained through the following steps: using 1 multiplied by 10 to the power of negative 5 as the base value; multiplying the current key priority by the key priority coefficient between 0.3 and 0.8; adding the product to 1; and then multiplying the base value by the sum to obtain the packet error rate threshold.

[0015] Furthermore, the interference identification model is InterferenceClassifierNet, which is built based on a deep convolutional network and a dual-channel attention mechanism. Its input is a joint feature vector of spatial and frequency domains, and its output is the interference type and the corresponding confidence level.

[0016] This invention also provides a star-flash keyboard anti-multi-source interference communication device that integrates Polar codes and SLB algorithm, comprising:

[0017] a. Radio frequency front-end, integrating a quad cross-shaped directional antenna array and a dual-channel spectrum analysis module, supporting beamforming and real-time spectrum scanning;

[0018] b. Baseband processing unit, equipped with multi-mode Polar encoder and SLB intelligent decision engine, can dynamically adjust the bit rate and switch working modes based on the RF front-end sensing results;

[0019] c. Cooperative control subsystem, including a three-dimensional parameter mapping table and a QoS scheduler, is used to associate and allocate interference characteristics, key priorities and communication resources;

[0020] d. High-speed data bus, used for transmitting control commands and real-time data between modules.

[0021] Furthermore, the RF front end updates the eight beam templates in milliseconds through a phase control network and uses a pattern null suppression strategy to reduce the signal power in the interference direction.

[0022] Furthermore, the baseband processing unit incorporates a deep reinforcement learning-based CodingModeRL model, which can jointly optimize the Polar code length, frozen bit position, and frequency hopping sequence to maximize key-weighted throughput.

[0023] The present invention also provides a computer-readable storage medium having a computer program stored thereon, the computer program implementing the above-described method when executed by a processor.

[0024] The present invention also provides a star-flash keyboard communication system, including the above-mentioned device and a host-side adaptation module; the host-side adaptation module includes a reverse channel monitoring unit and a parameter negotiation interface, used to establish an encrypted handshake with the device, synchronize interference classification information and perform end-to-end adaptive transmission.

[0025] Based on the above technical solutions and the technical problems solved, the advantages and positive effects of the technical solution to be protected by this invention are as follows:

[0026] This invention addresses the pain point of frequent link jitter caused by the superposition of Wi-Fi, Bluetooth, and custom ISM signals in high-density wireless environments such as industrial production lines, e-sports arenas, and complex offices. It constructs a three-in-one adaptive communication system: "Polar code error control + SLB intelligent load balancing + directional beamforming." Through electromagnetic fingerprinting and key priority mapping during the environment initialization phase, this solution completes multi-dimensional baseline calibration for spatial, frequency, and service layers from the very beginning of link establishment, laying a precise and traceable data foundation for subsequent real-time scheduling.

[0027] Leveraging the spatial null suppression of the quad-element cross antenna array and dual-channel spectrum heatmap analysis, the system can maintain a packet error rate of less than 10 to the power of -5 even in a -5 dB signal-to-noise ratio scenario. In actual tests, it can simultaneously suppress three channels of co-channel interference without interrupting key transmission. During the adaptive transmission phase, the microsecond-level switching logic, combined with an end-to-end latency of 1 x 2 milliseconds, ensures that even e-sports-level keystrokes are smooth without noticeable stuttering. Dynamic encoding and intelligent sleep strategies further reduce average power consumption by one-third, bringing a qualitative leap in battery life performance to wireless mechanical keyboards.

[0028] As supporting evidence of inventiveness, this invention breaks through the existing single-dimensional anti-interference framework that relies solely on frequency hopping or static FEC. It organically integrates machine learning-driven interference type identification, dynamic frozen bit replacement of Polar codes, and key service priority mapping, achieving for the first time a three-dimensional coupling optimization of "interference intensity - channel reliability - service weight". This coupling mechanism is based on a load balancing model with gradient approximation solution. According to comparative tests by a third-party laboratory, it improves throughput by 22 percentage points in a typical office environment without any additional hardware cost, fully demonstrating its technological advancement and industrial feasibility.

[0029] This solution addresses the long-standing technical challenge of balancing reliability and energy efficiency under high-concurrency interference in wireless input devices, a problem that has garnered widespread attention in the industry but remains unsolved. Within the same chip area and RF power amplifier budget, it achieves millisecond-level link elastic reconstruction and a 35% improvement in battery life, providing sustainable and mass-producible underlying communication support for future ultra-dense wireless office and immersive interaction.

[0037] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0038] In industrial-grade wireless peripheral applications, the primary challenge faced by the StarSpark keyboard is the broadband superposition interference from industrial control Wi-Fi, Bluetooth, and various custom ISM devices, manifesting as a surge in link transient bit error rate and key response jitter. The proposed solution first establishes a multi-directional beamformation using a four-element cross-shaped array, obtaining the interference wave angle distribution through coherent phase measurement. Then, a dual-channel real-time spectrum analyzer is used to construct a full-bandwidth power spectral density heatmap, extracting the interference power statistical moments within a second-level time window to form a dynamic electromagnetic environment fingerprint. This fingerprint accumulates over time, reflecting the migration of spatial-frequency interference patterns caused by workstation relocation and equipment start-up / shutdown, providing traceable underlying data for subsequent parameter tuning.

[0039] The interference identification process introduces a joint spatial-frequency domain feature vector, which is then processed by InterferenceClassifierNet to output the interference category and signal-to-noise correction factor. This network employs multi-scale convolutional kernels and a dual-channel attention gating mechanism, enabling it to simultaneously capture the spectral drift of narrowband frequency-hopping signals and the broadband OFDM energy grid, avoiding the instability of traditional energy detection in classifying multi-peak interference. The output is smoothed using a sliding window Kalman filter to eliminate isolated misclassifications and then fed into the SLB scheduling core to calculate the load threshold.

[0040] The SLB intelligent load balancing algorithm generates a three-dimensional resource map based on interference level, key priority, and link buffer status within a sub-millisecond timescale of key event arrival. The algorithm employs a dual-objective optimization model, using key-weighted throughput and average retransmission count as joint objectives, and obtains the optimal map in real-time through gradient approximation. The mapping results provide a Polar code frozen bit mask, code length selection, and frequency hopping sequence configuration, achieving hardware-software coordinated link reconstruction.

[0041] The Polar code implementation employs a CRC-assisted SCL-64 list decoder, combined with a dynamic frozen bit replacement strategy, to shift critical information bits to the higher bits of the reliable channel sequence when interference intensity is high. The coding rate R adaptively shrinks according to R = 0.75 e^{-α·Inorm}, and can be reduced to a minimum of 0.25, thus maintaining a better than 10 even under extreme collisions. -5 The packet error rate is [not specified]. The decoder uses a parallelized topology internally to ensure that the decoding latency does not exceed 60μs even at the highest list depth.

[0042] The RF front-end is based on an FPGA-driven 8×1 phased array network, which updates the beam coefficient in real time to form null suppression power in the interference direction. For unknown interference, it calls an ultra-wideband frequency hopping sequence, which is generated by pseudo-random Gold code. The hardware is interconnected with the baseband stage through a 10Gbps AXI-Stream bus. The loop delay plus the Baseband Pipeline control does not exceed 4μs, ensuring that mode switching is imperceptible to the user.

[0043] During long-term operation, the system writes link statistics to the local NVM and periodically reports them to the cloud-based analysis platform. The cloud uses a federated incremental learning framework to retrain InterferenceClassifierNet, and then pushes the updated quantized model to the terminal via OTA, achieving model aging and self-healing. This closed loop enables devices to maintain picosecond-level button jitter and sub-1% packet loss rate even in high-density wireless environments, providing a reliable human-computer interaction link for industrial automation, e-sports, and immersive input scenarios.

[0044] like Figure 1 As shown, this embodiment of the invention provides a method for anti-multi-source interference communication using a star-flash keyboard that integrates Polar codes and SLB. The method specifically includes:

[0045] S1: Environment initialization and baseline scanning. During the startup phase, the four-element cross-shaped directional antenna array is precisely calibrated to establish beam radiation templates in eight directions. At the same time, the working frequency band is scanned across the entire bandwidth using a high-precision spectrum analyzer to build an electromagnetic environment fingerprint database containing key parameters such as Wi-Fi hotspot distribution and Bluetooth device activity. Key priority mapping relationships are also established based on user habits.

[0046] S2: Real-time multi-dimensional interference perception. In the spatial domain, the phase difference measurement technology of the antenna array is used to accurately calculate the angle of arrival of the interference signal. In the frequency domain, the fast Fourier transform is used to analyze the spectrum occupancy in real time. In the time domain, the burst statistics of bit error rate are used to distinguish between instantaneous interference and continuous interference. These perception data are sent to the intelligent decision engine for comprehensive analysis. Based on the pre-trained machine learning model, the interference type and its characteristic parameters are accurately identified.

[0047] S3: Intelligent decision-making and parameter optimization, dynamically adjusts the working mode according to real-time interference characteristics, and adopts differentiated response strategies for different types of interference;

[0048] S4: Adaptive transmission execution, which combines strong error correction coding and directional antenna technology during periods of high interference, and switches to high-efficiency transmission mode in low-interference environments. Through a microsecond-level fast switching mechanism, it ensures seamless connection of the mode conversion process.

[0049] S5: Dynamic optimization and learning, regularly updating the interference feature database, and continuously optimizing the classification model and decision rules through online learning.

[0050] Furthermore, in S3, differentiated response strategies are adopted for different types of interference: when Wi-Fi interference is detected, an anti-collision coding scheme is automatically selected and directional beams are enabled; when Bluetooth interference is encountered, a dedicated channel is switched and the coding protection strength is increased; for unknown interference, an adaptive frequency hopping and redundant transmission mechanism is activated, and hierarchical protection is implemented according to the button priority.

[0051] Furthermore, in S3, the dynamic adjustment of the Polar code coding rate R satisfies the formula:

[0052] R = R0.exp(-α.I norm )

[0053] In the formula, R0 is the initial coding rate of 0.75, α is the interference sensitivity coefficient, which takes a value of 1.2 to 1.8, and I... norm The normalized interference intensity is 0 to 1.

[0054] Furthermore, in step S5, when a decline in communication quality is detected, a parameter reconfiguration process is immediately triggered, while user behavior patterns are continuously analyzed.

[0055] Furthermore, the trigger threshold for the reconfiguration process satisfies the formula:

[0056] T PER =10 -5 .(1+β.P key )

[0057] In the formula, β is the bond priority coefficient (0.3–0.8), and P... key The current button priority is 0 to 1.

[0058] Another objective of this invention is to provide a star-studded keyboard anti-multi-source interference communication device based on the aforementioned fusion of Polar codes and SLB. This device adopts a modular, layered architecture design, comprising:

[0059] The radio frequency front end integrates a quad cross-shaped antenna array and a dual-channel spectrum analysis module, and achieves dual interference detection in the space-frequency domain through beamforming technology and real-time spectrum scanning.

[0060] The baseband processing unit includes a multi-mode Polar encoder and an SLB intelligent decision engine, which supports dynamic bitrate adjustment and optimal transmission strategy generation.

[0061] The collaborative control subsystem intelligently associates interference characteristics, key priorities, and communication parameters through a three-dimensional parameter mapping table, and works with the QoS scheduler to achieve optimal resource allocation.

[0062] Furthermore, the modules are interconnected via a high-speed data bus.

[0063] Furthermore, the RF front-end integrates a four-element cross-shaped directional antenna array and a dual-channel spectrum analysis module, achieving dual interference detection in the space and frequency domains through beamforming technology and real-time spectrum scanning, specifically including:

[0064] The four-element cross-shaped directional antenna array consists of four directional antenna elements arranged in a cross shape. During the startup phase, it completes precise calibration and establishes beam radiation templates in eight directions. The angle of arrival of interference signals can be calculated through phase difference measurement technology.

[0065] By combining beamforming technology, the radiation direction of the antenna array is dynamically adjusted to create directional gain for the target signal while suppressing signals in the interference direction.

[0066] The dual-channel spectrum analysis module performs real-time full-bandwidth scanning of the operating frequency band to obtain spectrum occupancy parameters such as Wi-Fi hotspot distribution and Bluetooth device activity, and builds an electromagnetic environment fingerprint database.

[0067] By analyzing the frequency domain characteristics through Fast Fourier Transform (FFT), the spectral overlap region of co-channel interference signals can be identified, providing frequency domain data support for subsequent channel switching and coding adjustments.

[0068] Space-frequency domain collaborative detection mechanism: The spatial domain angle of arrival measurement of the antenna array is combined with the frequency domain feature recognition of the spectrum analysis module to achieve dual localization of the spatial orientation and frequency distribution of the interference signal.

[0069] Interference data in the spatial and frequency domains is transmitted to the intelligent decision engine in real time, providing basic data for the generation of differentiated anti-interference strategies.

[0070] Another object of the present invention is to provide a computer device, the computer device including a memory and a processor, the memory storing a computer program, the computer program being executed by the processor causing the processor to perform the steps of the star-flash keyboard anti-multi-source interference communication method that integrates Polar codes and SLB.

[0071] Another object of the present invention is to provide a computer-readable storage medium storing a computer program, which, when executed by a processor, causes the processor to perform the steps of the star-blink keyboard anti-multi-source interference communication method that integrates Polar codes and SLB.

[0072] like Figure 2 As shown in the figure, the present invention provides a star-flash keyboard anti-multi-source interference communication device that integrates Polar code and SLB. The device adopts a modular hierarchical architecture design, with the baseband processing unit as the core, the radio frequency front-end as the sensing and execution mechanism, and the collaborative control subsystem as the intelligent hub, to build a complete anti-interference communication system.

[0073] The RF front-end integrates a four-element cross-shaped directional antenna array and a dual-channel spectrum analysis module, achieving dual interference detection in both the space and frequency domains through beamforming technology and real-time spectrum scanning. The baseband processing unit includes a multi-mode Polar encoder and an SLB intelligent decision engine, supporting dynamic rate adjustment and optimal transmission strategy generation. The collaborative control subsystem intelligently associates interference characteristics, key priorities, and communication parameters through a three-dimensional parameter mapping table, working with a QoS scheduler to achieve optimal resource allocation. All modules are interconnected via a high-speed data bus, forming a closed-loop control link from environmental perception and intelligent decision-making to adaptive execution. The directional antenna array and encoder work together to maintain stable communication at a -5dB signal-to-noise ratio, while real-time data interaction between the spectrum analyzer and the SLB engine ensures rapid interference avoidance at the 50μs level. The dynamic feature database provides the system with continuous learning and evolution capabilities. The entire device is hardware-accelerated on the Nordic nRF54H20 platform, ultimately achieving a 1.2ms response latency and 10 -5 High-performance metrics for bit error rate.

[0074] This invention is applicable to short-range wireless terminals that have extremely high requirements for input real-time performance, anti-interference capability, and battery life.

[0075] Typical products implemented include:

[0076] 1. Gaming-grade Starlight Mechanical Keyboard: Can coexist with dozens of Wi-Fi 6E and Bluetooth 5.3 signals at large-scale events while still maintaining sub-millisecond key response;

[0077] 2. Industrial Human-Machine Interface Handheld Controller: Provides a stable control link for AGV scheduling and robot teaching in the complex electromagnetic environment of automated production lines;

[0078] 3. XR interactive handles and medical sterile keyboards: Ensure low latency and high reliability input in operating rooms or immersive presentation spaces with significant metallic reflections and multipath effects.

[0079] In the multi-source jamming chamber built in the experimental center, with three channels of 802.11ax and two channels of custom FHSS jamming enabled, when the signal-to-noise ratio dropped to -5 dB, the proposed solution still measured a packet error rate of less than 10 to the power of -5. Compared with the traditional frequency-hopping Bluetooth solution, the error rate decreased by two orders of magnitude, which is equivalent to an 8 dB encoding / decoding gain and three-channel interference suppression capability.

[0080] The link delay was sampled 100 times using a Tektronix MSO68B mixed-domain oscilloscope. The average end-to-end delay was 1.2 milliseconds, and the 95th percentile was 1.4 milliseconds. The beam null was triggered within 30 microseconds after the interference occurred, and the coding mode switch was completed within 50 microseconds. No key code loss or repeated triggering was observed during the switching process.

[0081] Under continuous typing load (80 bytes per second), the prototype powered by a 3000mAh lithium battery draws an average current of 14.8mA; compared to 22.6mA for a Bluetooth keyboard of the same size, power consumption is reduced by 35%. The equivalent battery life is increased from 120 hours to 162 hours, and thermal imaging shows that the controller's maximum casing temperature is below 41 degrees Celsius, meeting all-weather ergonomic temperature rise limits.

[0082] It should be noted that embodiments of the present invention can be implemented in hardware, software, or a combination of both. The hardware portion can be implemented using dedicated logic; the software portion can be stored in memory and executed by a suitable instruction execution system, such as a microprocessor or dedicated-design hardware.

Any modifications, equivalent substitutions, and improvements made by those skilled in the art within the scope of the technology disclosed in the present invention, and within the spirit and principles of the present invention, should be covered within the scope of protection of the present invention.
