Patent ID: 8379743

Claim:
A method of compensating interference of received symbols in a multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) receiver, which method includes: applying a minimum mean squared error (MMSE) equalization technique and a log likelihood ratio (LLR) scaling technique to received symbols vector (y) to obtain equalized and scaled symbols to be supplied to a decoder of said OFDM receiver, said equalization and scaling performed in merged manner by means of a single algorithm which comprises: obtaining a channel matrix (H) from a channel estimator of the receiver; generating an equivalent channel matrix (R) by multiplying said channel matrix (H) with its hermitian (H H ); determining an interference compensation matrix (F) from said equivalent channel matrix (R); and generating a product of said interference compensation matrix (F), said hermitian (H H ) of the channel matrix (H) and the received symbol vector (y) to obtain said equalized and scaled symbols.
