| 摘 要： | 基于周期为2m-1的二元伪随机序列,利用交织法构造了一类满足一定条件的周期为2m+1-1的基序列集,进而利用这些基序列集构造得到了一类参数达到Tang-Fan-Matsufuji界的二元最佳低相关区序列集。这类低相关区序列集具有更多的序列数目,应用到准同步CDMA系统可以支持更多的用户。

| Abstract: | Based on binary pseudorandom sequences with period 2m-1,A new construction of column sequence sets with period 2m+1-1 was presented.With these column sequence sets,one can get a new class of binary low-correlation zone(LCZ) sequence sets whose parameters can reach the Tang-Fan-Matsufuji bound.These LCZ sequence sets have larger set size,as a result,they can be used in quasi-synchronous(QS) CDMA systems to support more users. |
