摘要

摘要

En 中文
In this letter, we propose a low complexity decoding algorithm for majority-logic decodable nonbinary low-density parity-check (LDPC) codes. The proposed algorithm is initialized with the quantized squared Euclidean distances between the constellation points and the received signals. Like most of the existing reliability-based decoding algorithms, the proposed algorithm requires only integer operations and finite field operations and (hence) can be implemented with simple combinational logic circuits in practical systems. Simulation results show that the proposed algorithm suffers from a little performance degradation compared with FFT-QSPA. The algorithm provides a candidate for trade-offs between performance and complexity.
