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 utilises two phases, the first of which includes locating an optimum regularisation 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 regularisation parameters range located from the first phase.
