摘要
在现有分组码编码译码基础上提出了一种新的分组编码和译码算法。详细介绍了交叠编码的过程,由3个短信息分组相互交叠进而由现有分组码进行编码和缩短;以及译码的流程,详细讨论了两种不同的迭代译码。仿真分析了两种算法的性能差异,并将算法1进行了推广。最后总结两种算法的优缺点。
In this paper,a new coding algorithm based on known block code is proposed. Each new k-bit block is constructed by three short-message blocks across overlapping bits on fixed position,and then these new blocks are coded,finally the codes are shortened. The decoding blocks are reconstructed by received sequences across appending same fixed bits,and decoded with iterative algorithm. The difference of two algorithms is discussed through simulation,and algorithm 1 is extended. Finally,the shortcomings and merits of this new coding algorithm are summarized.
