Abstract
A coherent multiuser decorrelating detector for an asynchronous CDMA, time-varying Rayleigh fading channel is proposed and analysed. The detector uses fractionally sampled correlators outputs at time instants corresponding to users relative delays to simultaneously achieve two goals: the novel realisation of a one-shot decorrelator with lower computational complexity; and to exploit a form of the time diversity for improved error performance compared to symbol spaced sampling
