The present invention relates to a method of compensating interference of received symbols in a MIMO OFDM receiver employing MMSE equalization and LLR scaling, and to a MIMO OFDM receiver comprising a linear MMSE equalizer. The object to provide a low-complexity, numerically robust method for compensating interference of received symbols and to provide a low-cost, robust digital baseband receiver for MIMO-OFDM is achieved by merging linear MMSE equalization and scaling of the corresponding equalized symbols into a single algorithm that, for the 2xM MIMO case, completely avoids computationally extensive matrix inversion and allows for significant simplification of symbol detection as compared to separate equalization and scaling is achieved.
