Abstract :
We investigate the performance of several suboptimal multiuser detectors for rapidly time varying mobile radio channels. A modified Jakes (1974) model is used to simulate a realistic mobile fading channel. The use of the Kalman filter for this channel model is examined. We also analyze the performance of several noncoherent multiuser detectors. Analysis and simulation results indicate that the decorrelator is more robust than other considered multiuser detectors
