Abstract
Description
Technical Field
[0001] This invention relates to the fields of general signal processing, multi-source signal coupling correction, timing stabilization, frequency steady-state correction, and integrated hardware and software signal modulation technology. In particular, it relates to a multi-dimensional signal correction system and method that covers multiple correction modes, all hardware and software deployment scenarios, and is adaptable to all-domain network applications. Background Technology
[0002] Existing signal correction technologies are limited in scope and fragmented, only capable of simple corrections for single signals, frequencies, and sequence, leaving significant technological blind spots. The industry generally relies on external reference equipment, failing to achieve independent, self-stable signal generation; mechanisms for cross-domain heterogeneous signal linkage, historical timing backtracking, and full-form gain adjustment have long been lacking. Meanwhile, existing technical solutions have limitations in protection boundaries, mostly limited to the algorithm level, not adapted to general hardware carriers and embedded software, unable to cover multi-device networking joint application scenarios, and easily circumvented through hardware modification, software rewriting, and scenario splitting. They lack a closed-loop correction architecture that is universally applicable, integrates hardware and software, and is compatible with networking. Summary of the Invention
[0003] This invention overcomes the shortcomings of existing technologies and constructs a comprehensive, multi-dimensional signal coupling correction underlying architecture that is not limited to any particular scenario, industry, or deployment platform, and covers various signal correction paths from a physical logic perspective. This invention comprehensively covers seven calibration dimensions, with each module performing its specific function and working in synergy to form a comprehensive calibration system: The signal attribute dimension enables cross-domain linkage and complementary correction of signals of the same, same, and different types, solving the pain point of traditional technologies' inability to correct cross-type signals; the timing dimension covers real-time and non-real-time scenarios through simultaneous and different timing real-time correction and historical timing backtracking correction, effectively suppressing the accumulation of timing errors; the frequency operating condition dimension enables phase and amplitude stabilization of signals at the same frequency, frequency difference matching of signals at different frequencies, and cross-frequency compensation, adapting to complex electromagnetic environments across the entire frequency band; the calibration source quantity dimension supports flexible switching between single and multiple sources, adapting to the calibration reliability requirements of different scenarios; the continuous operation mode dimension allows switching between continuous and intermittent correction according to the scenario, balancing high precision and low power consumption requirements; the operating condition dimension covers active reference coupling and passive silent backtracking coupling, achieving bidirectional adaptation between high-precision calibration and long-term steady-state self-stabilization; and the channel scheduling dimension supports timed rotation, untimed dynamic switching, and single-multi-channel collaboration, ensuring channel stability and anti-interference capabilities. This invention pioneers a cross-domain coupling mechanism for heterogeneous signals and a historical time-series backtracking coupling mechanism, coupled with a full-form gain adjustment system, to achieve deep signal binding, error complementarity, and collaborative linkage. The system supports various deployment methods, including pure hardware, pure software, and a combination of hardware and software, and is compatible with all types of signal processing hardware and embedded control software. It supports stand-alone operation and multi-device cross-domain network collaborative correction. The system supports both independent operation without external power and compatibility with external auxiliary calibration modes, effectively solving industry pain points such as passive error accumulation, attenuation over ultra-long distance transmission, and easy technical avoidance. Detailed Implementation 1. Active high-precision networking mode: Multiple nodes actively transmit reference signals, real-time bidirectional coupling and mutual calibration, heterogeneous signal linkage to correct carrier state, adaptive matching active gain amplification, to achieve high-precision calibration and ultra-long-distance transmission. 2. Passive silent self-stabilizing mode: Active transmission is turned off, multiple sets of historical timing data are retrieved, signal parameters are maintained through backtracking coupling correction, and low-power long steady-state operation is achieved by passive loss compensation. 3. Short-range simplified mode: It adopts direct transmission without amplification + single-channel self-calibration to achieve simplified, low-power short-range signal transmission. 4. Interplanetary relay-free mode: Relying on heterogeneous coupling to drive active gain amplification and compensate for cross-planetary transmission loss, it can achieve long-distance stable phase sensing without relying on relay satellites. 5. Mixed-signal chip mode: The amplitude and phase of the analog radio frequency carrier are corrected by using a digital timing reference signal, or the timing deviation of the digital processor is corrected by using an analog reference clock, so as to achieve end-to-end signal self-stabilization within the chip. 6. Hardware and software adaptation application mode: The calibration architecture is embedded in various signal processing hardware circuits and equipped with matching embedded control software to achieve native signal self-stabilization of the device. 7. Cross-domain networking and collaborative mode: Multiple types of terminal devices work together through software and hardware to achieve cross-domain joint calibration of communication, radar, timing and industrial control equipment, and complete the steady-state synchronization of signals across the entire domain. Beneficial effects 1. Full coverage: Covers multiple signal correction and gain adjustment techniques, with various related technologies falling within the protection scope, significantly reducing the possibility of circumvention; 2. Universal at the underlying level: Not tied to any specific industry, it can cover all signal processing fields such as communications, navigation, aerospace, radar, chips, precision measurement and control, and autonomous driving; 3. Elimination of external dependence: Achieving pure independent, reference-free self-stabilization, effectively eliminating dependence on external equipment; 4. Breakthrough in interplanetary communication: Adaptive gain driven by heterogeneous coupling enables relay-free interplanetary transmission, optimizing traditional deep-space relay architecture; 5. Collaborative and coordinated operation: The various correction mechanisms are deeply integrated and coordinated, and any partial misappropriation, dismantling, or modification of the technology can easily constitute infringement; 6. Complete hardware and software closed-loop protection: Simultaneously locking in the three major implementation dimensions of hardware carrier, software algorithm, and networking application, significantly reducing the paths to circumvent infringement by modifying hardware, modifying code, or dismantling scenarios; 7. Adaptable to commercial licensing: Unified adaptation to software and hardware products and networking projects across all industries, with no industry or equipment form restrictions, and adaptable to standardized unified licensing and profit-sharing models of major manufacturers.
