提出了一种基于分层最小和算法的低复杂度神经网络循环码译码器。通过将分层最小和算法推广到神经网络,在保持良好纠错性能的同时减少了网络权值的数量。选择Bose-Chaudhuri-Hocquenghem(BCH)码、二次剩余(QR)码和穿孔Reed-Muller(RM)码作为三个示例性二进制循环码。仿真结果表明,与现有的神经网络解码器相比,该神经网络解码器具有更低的计算复杂度和更优越的上级性能。此外,神经解码器结合修改的随机冗余解码(mRRD)算法进行了研究,以接近一些短码的最大似然解码的性能。
This paper proposes a low-complexity neural network decoder based on the layered min-sum algorithm to decode cyclic codes. By generalizing the layered min-sum algorithm to its neural network counterpart, the number of network weights decreases while retaining a good error correction performance. The Bose–Chaudhuri–Hocquenghem (BCH) codes, quadratic residue (QR) codes, and punctured Reed–Muller (RM) codes are selected as three exemplary binary cyclic codes. Simulation results show that the proposed neural decoder achieves superior performance with less computational complexity compared with the state-of-the-art neural network decoder. Further, a neural decoder incorporating the modified random redundant decoding (mRRD) algorithm is investigated to approach the performance of maximum-likelihood decoding for some short codes.
