Abstract :
An overview of the performance of CDMA networks which overlay narrowband signals in order to increase the spectral efficiency is presented. Such systems employ interference suppression filters in the CDMA receivers to minimize the interference caused by the narrowband waveforms. The results presented in this paper include the effects of multipath fading, as well as both intracell and intercell interference for cellular systems
