ABSTRACT
Code division multiple access (CDMA) is a most promising technique for using channel efficiency. Multiple access interference (MAI) is a limiting factor for the capacity of CDMA system. Proposed design is based on the step by step practical implementation of matched filter (MF) detection and minimum mean squared error (MMSE) detection. Thus, providing flexibility of variations in all parameters of interest which are otherwise difficult to accommodate in a theoretical model. In this paper, matched filter, decorrelating filter and MMSE and other detection techniques have been proposed to alleviate the effects of the MAI.
