However, there are some limitations of traditional spread spectrum sequence: if spreading gain is certain, the number of available sequences is limited; performance of cross-correlation function rapidly declined when partial cross-sorrelation was done.
然而,传统扩频码有一定的局限性:在扩频增益一定的情况下,可用的地址码数目有限;部分互相关时,其相关函数性能迅速下降。
