Abstract
The invention relates to a method and apparatus for use in the channel estimating in a manner which reduces Bit Error Rate (BER) and/or Mean Square Error (MSE) and allows the channel estimation to be performed in an efficient manner but with reduced complexity. The method utilizes two phases, the first of which includes locating an optimum regularization parameters range from an initially larger range; and a second phase of obtaining optimum channel estimates from a Tikhonov regularized least squares solution using the optimum regularization parameters range located from the first phase.
