Abstract :
A major advantage of spread-spectrum communication systems is their ability to exploit the multipath structure of the received signal. Different paths can be characterized by their time delays, attenuations, and angles of arrival. A standard RAKE receiver recombines different path signals and mitigates the effects of multipath by separating the paths in time domain. A method of exploiting the spatial properties of the multipath environment using multiple element antenna arrays is proposed where both code and spatial structure of signals can be used to improve SINR. The simulation results present the performance of such a multichannel receiver
