Abstract
Methods and apparatus for reducing complexity of MMSE computations in a receiver are disclosed. According to these methods and apparatus, a first MMSE matrix is computed for a first sub-carrier in a pre-defined group of sub-carriers of a received transmission frame at a receiver. The first MMSE is based on a pilot signal of the first sub-carrier. The first MMSE matrix may then be phase shifted to compute a second MMSE matrix for a second sub-carrier in the group, the phase shifting based on a variation in column and row between the pilot signal of the first sub-carrier and a symbol of the second sub-carrier of the transmission frame.
