Description

Technical Field

[0001] This invention relates to the field of photonic information processing and broadband signal reception technology, specifically a broadband parallel information processing device and method driven by high-dimensional photonic multiplexing, which is applicable to the real-time reception and processing of high-frequency, broadband, multi-dimensional electromagnetic signals in systems such as radar, communication, and electronic reconnaissance. Background Technology

[0002] In fields such as radar, communications, and electronic reconnaissance, modern electromagnetic signals exhibit typical characteristics of wide spatial coverage, broad frequency range, and large dynamic range in the energy domain, placing extremely high demands on the real-time performance and multi-dimensional information processing capabilities of receiving and processing systems. However, traditional processing architectures based on electronic technology face two fundamental bottlenecks: On the one hand, at the signal reception level, due to the electronic bottleneck of analog circuits, the bandwidth of the received signal is always limited, making it difficult to achieve full-frequency coverage reception of the signal.

[0003] On the other hand, at the data processing level, as the array size and signal bandwidth increase, the amount of data that the system needs to process grows exponentially. Digital processing architectures based on CPUs, GPUs, or FPGAs face enormous computational throughput pressure when executing complex algorithms such as beamforming and spatiotemporal adaptive processing. To improve processing efficiency, existing technologies mostly adopt parallel computing schemes in the digital domain, splitting data to multiple processing cores through serial-to-parallel conversion. However, this "post-parallel in the digital domain" mode has inherent defects: on the one hand, it requires the front-end ADC to have an extremely high sampling rate, which is close to the current limits of electronic technology, and the resulting high-speed data flow places stringent requirements on the bandwidth of the transmission interface and large-capacity buffers; on the other hand, after large-scale channel splitting in the digital domain, it is difficult to guarantee strict timing synchronization and amplitude-phase consistency between each parallel branch, which is the key to achieving high-precision array processing.

[0004] Photonic information processing technology, with its unique advantages of broadband, high speed, and multi-dimensional physical dimensions (such as wavelength and mode), provides a new approach to overcoming the aforementioned bottlenecks. Wavelength division multiplexing (WDM) and mode division multiplexing (MDM) technologies have laid the physical foundation for building large-scale parallel processing systems. However, existing photonic-assisted schemes still have significant shortcomings: most schemes only use photonic technology to implement a single functional module (such as an optical delay line), and the core processing still relies on electronic circuits, failing to fundamentally get rid of the electronic bottleneck; although some schemes introduce the idea of ​​optical parallelism, they implement key steps such as optical frequency comb generation, time-domain discretization, and decomposition as discrete subsystems, resulting in complex system structure, poor stability, and difficulty in ensuring long-term consistent synchronization and amplitude-phase accuracy between channels.

[0005] Therefore, there is an urgent need for an innovative solution that can deeply integrate the advantages of photonic parallel processing and simplify and coordinate key optical processing steps at the architectural level to solve the problem of efficient, low-latency, and high-consistency processing of multidimensional massive broadband signals. Summary of the Invention

[0006] This invention addresses the problem of existing electromagnetic receiving and processing systems' inability to handle massive amounts of multidimensional data. It proposes a high-dimensional photon multiplexing-driven broadband parallel information processing device and method. By jointly multiplexing M different wavelengths and N different modes, it simplifies three key parallel processing steps: frequency comb generation, time-domain discretization, and speed-down decomposition. This achieves unified multiplexing, in-phase driving, and coordinated reception and processing of M×N different analog signals within the same optical path. Simultaneously, utilizing an optical domain parallel processing architecture, it directly performs K-level time-domain parallel decomposition on the broadband signal in the analog optical domain, decomposing a single high-speed data stream into 2^K parallel low-speed sub-channels. The data volume and rate of each channel are reduced to 1 / 2^K of the original. This reduces the sampling rate required by the backend ADC and the DSP core operation clock, effectively avoiding the high-speed data transmission interface and large-capacity storage units required by traditional parallel computing. It represents an effective solution for future high-performance arrayed broadband multidimensional signal reception and processing.

By utilizing the joint multiplexing of M different wavelengths and N different modes, it simplifies the three key parallel processing processes of frequency comb generation, time-domain discretization, and rate-reduction decomposition. This achieves unified multiplexing, in-phase driving, and coordinated reception and processing of M×N different analog signals within the same optical path. This not only reduces the overall system complexity, size, and power consumption but also effectively ensures amplitude and phase consistency and high synchronization between channels.
