Abstract :
This paper presents aspects of incorporating diversity detection in DS-CDMA networks. A feasible solution proposed here is with the consideration of biphase information sequence and quadriphase pseudo noise spreading sequence. The receiver model functions with a combination of two parallel integrate and dump stages in use. Performance analysis by computer simulation is presented for a network where the ratio of length of spreading sequence to the number of users is 3.
