Abstract :
We propose an enhanced blind constrained minimum variance (CMV) CDMA receiver with joint channel estimation for frequency selective channels. We develop a CMV solution for multipath using a recently proposed enhanced correlation matrix and investigate the performance of the proposed approach with a low complexity blind channel estimation algorithm based on the power method. Simulation results show significant improvements for the proposed receiver design.
