Performance Analysis of Non-Orthogonal Codes for CDMA Wireless Systems (original) (raw)

The performance of a CDMA based wireless mobile systems is largely dependent on the characteristics of pseudorandom spreading codes. Thus, the choice of spreading codes is an important parameter to improve the performance of CDMA mobile systems. It is desirable to have a code dictionary consisting of spreading codes which possess both impulsive ACF and all zero CCF characteristics. Therefore, in this paper various non-orthogonal codes have been investigated with special emphasis on their peak as well as mean square correlation properties.
