This book is a self-sufficient text for various multiuser detection techniques that have been proposed to eliminate the effects of the Multiple Access Interference (MAI). The MAI is a major concerned factor for CDMA system because it causes an instability to the system which leads to excessive bit error rates and major drawback that limits the capacity of CDMA system. In this book the linear multiuser detection schemes have been considered which demodulates the signal that contains MAI.
