Title:
UNDERWATER ACOUSTIC COMMUNICATION SYSTEM BASED ON DECODING CASCADE ITERATION OF MONTE CARLO POLAR CODE
Document Type and Number:
WIPO Patent Application WO/2024/067178
Kind Code:
A1
Abstract:
Disclosed in the present application is an underwater acoustic communication system based on decoding cascade iteration of a Monte Carlo polar code. The system comprises: a transmitting end apparatus used for performing Monte Carlo polar code encoding and modulation processing on an initial sequence to obtain an OFDM signal and transmitting the OFDM signal; and a receiving end apparatus used for receiving a sound wave containing noise in an underwater acoustic channel and performing analog-to-digital conversion, mixed channel estimation, equalization, demodulation and Monte Carlo polar code decoding on the sound wave containing the noise to obtain a decoded sequence, wherein a Monte Carlo polar code decoder is cascaded with a mixed channel estimation module and an equalizer.
