In recent years, mobile communications has become very popular and the demand for its services has increased dramatically. The capacity of mobile communication systems is mainly limited by co-channel interference caused by frequency reuse. The acceptable co-channel interference at the receiver determines the minimum allowable distance between adjacent co-channel users and hence the system capacity. One approach to increase the capacity is to employ co-channel interference resistant receivers. The research work presented in this thesis deals with the designing of such receivers for cellular mobile communication systems.
