基于D序列部分互相关的CDMA系统
Partial Cross-Correlation of D-Sequences based CDMA System
摘要：
与其它伪随机序列一样，十进制序列可用于设计码分多址（CDMA）系统。它们似乎非常适合于此，因为在其周期的LCM上获取的d序列的互相关为零。但是，实际系统很可能不满足每个比特的码片数等于分配给不同用户的所有序列的LCM的条件。因此，有必要确定d序列的部分互相关特性。本文对d序列进行了实验，发现d序列的部分互相关小于PN序列，表明d序列可以有效地用于CDMA。
英文摘要：
Like other pseudorandom sequences, decimal sequences may be used in designing a Code Division Multiple Access (CDMA) system. They appear to be ideally suited for this since the cross-correlation of d-sequences taken over the LCM of their periods is zero. But a practical system will not, in most likelihood, satisfy the condition that the number of chips per bit is equal to the LCM for all sequences that are assigned to different users. It is essential, therefore, to determine the partial cross-correlation properties of d-sequences. This paper has performed experiments on d-sequences and found that the partial cross-correlation is less than for PN sequences, indicating that d-sequences can be effective for use in CDMA.
