摘要

利用交错运算，提出了一种基于完全互补码和正交矩阵的群间互补码的构造方法。所提出的IGC码由多组多子集组成，每个子集是一个z互补码。对于新型IGC码，其同组内不同子集的任意两个码之间的互相关函数(CCF)比同组内任意两个码之间的互相关函数(CCF)具有更宽的零相关带(ZCZ)，且不同组内任意两个码之间的互相关函数(CCF)处处为零。基于IGC码的码分多址(CDMA)系统在误码率上的性能优于基于常规码的传统限干扰CDMA系统。此外，新的IGC代码在同步和异步操作模式下都可以很好地工作。

Novel IGC codes with inter-subset zero-correlation zone for code division multiple access

With the aid of interleaving operations, a novel construction of inter-group complementary (IGC) codes is proposed based on perfect complementary (PC) codes and orthogonal matrices. The presented IGC codes which consists of multiple groups with multiple subsets and each subset is a Z-complementary codes. For the novel IGC code, its cross-correlation function (CCF) between any two codes of different subsets in the same groups have a wider zero correlation zone (ZCZ) than that of any two codes in the same subset and its CCF between any two codes of different groups are zeros everywhere. IGC codes based code division multiple access (CDMA) systems may perform better on bit error rates than conventional codes based traditional interference-limited CDMA systems. Moreover, the new IGC codes may work well in both synchronous and asynchronous operational modes.
