Application of Adaptive Antenna Array in the Receiver on Up-link of Wide-band CDMA

A novel spatial-temporal receiver structure for wide-band CDMA reverse link is proposed. This structure is based on the technical combination of adaptive antenna array and transversal filter, together with the chip-rate channel estimation and variable step-size adaptive algorithm. Theoretical analysis and computer simulation results show that the proposed structure has better receiving performance and faster convergence speed under Rayleigh fading environments.
