METHOD AND APPARATUS FOR PERFORMING CHANNEL EQUALIZATION ON A MIMO SIGNAL

摘要

A method is provided for performing channel equalization on a wireless signal. The method includes: (i) formulating an equalizer associated with sub-carriers of the wireless signal, wherein the equalizer is a function of a quantity relating to signal quality (305); (ii) determining an adjoint of the equalizer over a selected number of the subcarriers (310); (iii) interpolating the adjoint determined in (ii) to obtain an adjoint of the equalizer over remaining ones of the subcarriers of the wireless signal (315); and (iv) generating an equalized signal for each of the subcarriers using the adjoint of the equalizer over the selected number of subcarriers and the interpolated adjoint over the remaining ones of the subcarriers (320).
