Channel Estimation for RLS-Based Linearly Constrained Minimum Variance Receivers
César A. Medina, Raimundo Sampaio‐Neto · 2008
In this paper we use an alternative implementation of the RLS based linearly constrained minimum variance (LCMV) receiver for multicarrier (MC) CDMA systems. As a result of this implementation a new blind channel estimation algorithm is proposed. It is shown through computer simulations that the resulting receiver filter achieves nearly the same performance than previously proposed methods, while reduces the computational complexity.
