Abstract:
1. A method of decoding a received signal, the method comprising: receiving a signal with a receiver via at least one of first and second receive antennas, the signal being a function at least of a noise term matrix, of a channel matrix, and of a first and second symbols and belonging to at least a signal constellation, said channel matrix comprising a first and a second columns, said first column comprising components representing a propagation channel response between a first transmit antenna and at least the first and a second receive antennas, said second column comprising components representing the propagation channel response between a second transmit antenna and at least the first and second receive antennas, selecting with the receiver a set of possible values of the first symbol belonging to the signal constellation; for each selected value of the first symbol performing the steps of: selecting with the receiver the minimal Euclidean distance among the Euclidean distances respectively calculated for the different selected values belonging to the set or a subset of said set; and selecting with the receiver decoded first and second symbols corresponding to the selected minimum Euclidean distance.
