Abstract :
A novel pilot aided adaptive antenna array for reverse link of CDMA system is proposed in the paper. In this work, a sliding-window integrator is exploited to estimate channel parameters, and the weight of the antenna array is updated by using RLS algorithm in chip rate for tracing the channel variation fast. Theoretical analysis and computer simulation results show that this receiver has better receiving performance and faster convergence compared to the traditional symbol rate based algorithm under the Rayleigh fading environments.
