摘要

提出了一种将哈夫曼码、行列阵列(RAC)码和相位/频率调制相结合的技术，以减少冗余，提供错误保护，同时优化信道带宽。结果表明，与采用解调器然后是RAC代码的网格解码器和霍夫曼解码器相比，该方案提供了总体复杂性的降低。设计并实现了采用BFSK/MPSK调制的组合码格，并与采用编码和未编码MPSK调制的组合码格的误差性能进行了比较。提出的分组编码调制(BCM)方案既适用于数据传输，也适用于信息存储。

Combined Huffman code, row and column array code and phase/frequency modulation

A technique for combining Huffman code, row and column array (RAC) codes and phase/frequency modulation in order to reduce redundancy, provide error protection and simultaneously to optimise channel bandwidth is presented. It is shown that this scheme provides a reduction in overall complexity as compared to that employing a demodulator followed by a trellis decoder of RAC code and a Huffman decoder. The trellis of the combined codes employing BFSK/MPSK modulation are designed and implemented and their error performances are compared with those employing coded as well as uncoded MPSK modulation. The proposed block coded modulation (BCM) scheme is suitable for both data transmission and information storage.
