Patent ID: 8121209

Claim:
A method for decoding a signal vector in a multiple-input multiple-output transmission scheme, comprising: receiving, with a receiver, multiple signal vectors of a first dimension (N r ) corresponding to a common transmit signal vector of a second dimension (N t ), wherein each of the received signal vectors is associated with a channel response matrix of dimension N r ×N t ; concatenating, with vector combining circuitry, K of the received signal vectors into a combined received signal vector of dimension KN r , wherein K is an integer variable greater than one; concatenating, with matrix combining circuitry, K of the channel response matrices into a combined channel response matrix of dimension KN r ×N t , calculating a matrix parameter from the combined channel response matrix with processing circuitry, wherein the calculation comprises at least one of factoring the combined channel response matrix and inverting the combined channel response matrix; processing, with the processing circuitry, the combined received signal vector using the calculated matrix parameter to produce an equalized signal vector of dimension N t , wherein N t <KN r ; and decoding, with a decoder, the equalized signal vector using the combined channel response matrix.
