Design of High-Reliability LDPC Code Algorithm for Relay Satellite Communication System
Signal and Information Processing, Networking and Computers(2022)
摘要
This paper introduces a hardware platform and software algorithm for the design of relay satellite LDPC encoding and decoding, And use computer simulation method to simulate the performance of LDPC (8176, 7154) code normalization minimization decoding algorithm, determine the correction factor of the decoder through analysis and simulation verification. Compared with the uncoded system, the system can obtain a coding gain of about 7.0 dB, which is consistent with the index results given in the CCSDS standard.
