General MVDR smart antenna algorithm for frequency selective channels

The minimum variance distortionless response (MVDR) is a very well known algorithm to obtain the optimum weight vector which maximizes the output signal to interference and noise ratio (SINR) of multiple antennas. In this paper we propose the MVDR with linear constraint algorithm to be used in multipaths and frequency selective channels to capture the different paths signal components. The Rake receiver is used to coherently add the different signal components. The main aim of our generalization is to use one weight vector to capture all the signal components; this could significantly reduce the complexity and costs of spatial/temporal processing of CDMA cellular systems. The influence of the proposed algorithm on the achievable system capacity is investigated.
