Generation and Correlation Characteristics of Complex Spreading Sequences for CDMA Wireless Communication

Poonam Goyal; Deepak Kedia

This paper presents complex spreading sequences (CSS) for use in coded multiple access communication systems. The complex sequences such as Zadoff-Chu (ZC) and Oppermann {&} Vucetic (OV) are described here. These complex spreading sequences offers a very wide range of values for both auto-correlation (AC) and cross-correlation (CC) functions, allowing great flexibility in the selection of characteristics of sequence sets. The parameters such as mean-square aperiodic AC and CC values for various sequence sets are presented here.
