摘要

研究了瑞利衰落信道下多级编码(MLC)的速率设计规则。通过对16-QAM和Ungerboeck映射的仿真,推测编码指数规则在有限长度下仍然是最好的。采用低密度奇偶校验(LDPC)码的MLC方案在具有信道状态信息的全交错信道中,以10-5的误码率在超过容量限制的2dB内执行,带宽效率为2位/符号。LDPC方案在相关信道中遭受较小的信噪比损失。

Performance of low-density parity-check codes with 16-QAM in fading channels
The rate design rules for the multilevel coding (MLC) are studied over the Rayleigh fading channel. By simulations on 16-QAM and Ungerboeck mapping, it is speculated that the coding exponent rule is yet the best for finite length. The MLC scheme using low-density parity-check (LDPC) codes performs within 2dB above the capacity limit at the bit error rate 10-5 for bandwidth efficiency 2-bits/symbol in the fully interleaved channel with channel state information. LDPC schemes suffer less signal-to-noise ratio penalty in correlated channels.
