Abstract: Aiming at the problem that the current design method cannot achieve accurate sorting of laser-guided mixed signals, a design method of laser-guided mixed-signal sorting system based on self-coding network is proposed. and the design is based on this Including laser guidance signal receiving, processing, sorting, merger batching and sorting result sending module, forming a complete system software operation flow; and including decoding circuit, latch circuit, signal buffer circuit, and laser Guided signal uploading circuits and system selectors for peripheral auxiliary circuits are designed to achieve the final design of the laser-guided mixed-signal sorting system. Experimental results show that the proposed method can accurately achieve the sorting of general laser guidance signals and three special laser guidance signals including carrier frequency signals, pulse width signals and heavy frequency signals.
