Description: 硬判决和和积译码的性能相差不大，而最大似然译码的性能较好。因为最大似然译码的方法是找出所有发送码字中可能性最大的发送码字作为译码估值，是一种通过经验与归纳，由接收值推测发送码字的方法。-Hard decisions and the performance of the sum-product decoding little difference, the maximum likelihood decoding performance is better. Because the maximum likelihood decoding method is to find all the most likely sent codeword as a codeword decoding sending valuation, is a type of experience and induction, the value suggested by the received code words to send method.

Description: ：介绍了AWGN 信道基于高阶调制的软解调算法，研究了LDPC 码的和-积译码算法原
理，并对高阶调制的和-积算法及其简化算法进行了研究与性能仿真. 仿真结果表明采用高阶
调制的λ -min 和-积简化算法译码在降低了译码复杂度的同时可实现高速率数据的可靠传输-the high order soft demodulation algorithms based on AWGN were
introduced. Then the basic encoding and decoding principles of LDPC codes were studied, and the
sum-product algorithms with its reduced complexity algorithms were presented based on high order
soft demodulation. Simulation result shows that the coded-modulation algorithms can work reliably
in high speed digital communication. Platform: |
