摘要

针对多电平编码调制系统，提出了半代数低密度奇偶校验码。采用高斯近似法，根据每一级的码率对LDPC码的码参数进行优化。采用迭代多级译码(IMSD)方案，得到了明显的改进。在加性高斯白噪声(AWGN)信道上，分别对8PSK的Ungerboeck分区(UP)和混合分区(MP)系统性能进行了评价。研究结果表明，从硬件复杂度和系统性能的平衡角度出发，基于优化LDPC码、容量规则和MP构建的多电平编码调制系统是实现AWGN信道带宽高效传输的良好选择。

Design of semi-algebraic low-density parity-check (SA-LDPC) codes for multilevel coded modulation

Semialgebraic low-density parity-check (SA-LDPC) codes are proposed for the multilevel coded modulation system. We optimize code parameters of LDPC codes according to the rate of each level by Gaussian approximation. Iterative multistage decoding (IMSD) scheme is adopted to get the significant improvement. System performance with Ungerboeck partitioning (UP) and mixed partitioning (MP) for 8PSK is evaluated respectively over additive white Gaussian noise (AWGN) channels. Many results are presented, they indicate that in terms of the tradeoff between hardware complexity and system performance, constructed multilevel coded modulation system based on optimized LDPC codes, capacity rule and MP is a good choice for the bandwidth efficient transmission over AWGN channels.
