Abstract:
1. An apparatus configured to: generate a set of filter coefficients w from inverting a series of sub-matrices F, each of the sub-matrices of size no greater than 2×2 and representing an element of an approximated correlation matrix C wherein the apparatus is configured to generate the set of filter coefficients by combining, as a matrix multiplication F the apparatus further configured to perform an inverse fast Fourier transform on the result of the multiplying to resolve a filter matrix W whose elements w comprise the set of filter coefficients; and the apparatus is further configured, for each k with a combination {umlaut over (Γ)} k =[γ 1 (k)γ 2 (k)] of the k th elements of the channel coefficients h in the Fourier transformed channel matrix H.
