Title:
DECODING CASCADE ITERATIVE UNDERWATER ACOUSTIC COMMUNICATION SYSTEM BASED ON GAUSSIAN APPROXIMATION IMPROVED POLAR CODE
Document Type and Number:
WIPO Patent Application WO/2024/067173
Kind Code:
A1
Abstract:
Disclosed in the present application is a decoding cascade iterative underwater acoustic communication system based on a Gaussian approximation improved polar code. The system comprises: a transmitting end device, configured to perform polar code encoding and modulation processing on an initial sequence to obtain an OFDM signal, and transmit an acoustic wave comprising the OFDM signal; and a receiving end device, configured to receive an acoustic wave comprising noise in an underwater acoustic channel, and perform analog-to-digital conversion, hybrid channel estimation, equalization, demodulation and polar code decoding on the acoustic wave comprising the noise to obtain a decoded sequence.
