Abstract :
Telecommunications is experiencing a wireless revolution leading us to a world of personal communication services (PCS) which are expected to play a significant role in the future universal communication networks. CDMA is used to multiplex different services in a multimedia network where multiaccess interference is approximated as a Gaussian distribution. When Rayleigh fading is present in the channel, a RAKE receiver is employed to improve the performance. Power control for a single service network is adapted to incorporate multimedia requirements. Furthermore, various error control schemes based on Reed Solomon codes and convolutional codes are discussed taking account of the quality and delay constraints. Medium access control and the system capacity are also addressed
