1. 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 ; processing, with processing circuitry, the combined received signal vector 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.
