新的零相关区周期互补序列集的构造方法
New Construction Method for Periodic Complementary Sequence Sets with Zero Correlation Zone
摘要
Abstract
We propose two methods for constructing more spread sequences that conform to code-division multiple access (CDMA) systems. The first method involves the construction of new shift sequences by assigning different values to the length of the zero correlation zone. Based on these shift sequences, we construct new periodic complementary sequence sets with a zero correlation zone by utilizing the correlation properties of the perfect sequence, and combining the structural characteristics of the Hadamard orthogonal matrix with the interleaving technique. This method can adjust the length of the zero correlation zone, based on the requirements of different systems to accommodate a wider range of applications. In the second method, zero-correlationzone sequence sets are used as the initial sequence, and the Hadamard matrix is combined with the interleaving technique to expand the length of the zero correlation region. In both methods, the number of sequence sets is expanded so that more users can be supported at the same time in quasi-synchronous CDMA systems.关键词
