SUMMARY An effective design of multistage parallel interference cancellation (PIC) receiver using blind adaptive (BA) despreader and pre-respreader interference estimator for uplink CDMA is proposed and analysed. A novel algorithm is designed, which exploits constant modulus (CM) property of the users' transmitted signals and inherent channel condition to(More)
Distributed processing is an essential part of collaborative computing techniques over ad-hoc networks. In this paper, a generalized particle swarm optimization (PSO) model for communication networks is introduced. A modified version of PSO, called trained PSO (TPSO), consisting of distributed particles that are adapted to reduce traffic and computational(More)
— In this paper, we introduce blind adaptive interference cancellation for a practical uplink CDMA effected by multiple access interference (MAI) in cooperative communications systems scenario. During the collaboration phase, each paired users exchange their data to communicate with the base-station by using their own and pairing users' channels to achieve(More)
In this study, the authors propose a novel collaborative multiuser transmission and detection scheme for the uplink of code-division multiple access (CDMA) that exploits the differences between users' fading channel signatures to increase the user capacity well beyond the spreading length in multiple access interference (MAI) limited environment.
