Systems and methods for detecting data in a received multiple-input-multiple-output signal are provided. N signals are received from N respective antennas, where the received signals are associated with (i) M sets of data values, (ii) a set of symbols, and (iii) a set of carrier frequencies. The N signals are formed into a received signal vector y, and one or more transformations are performed on the received signal vector y to obtain a transformed vector. A plurality of samples are formed from the transformed vector. For samples of the plurality of samples, a data detection technique of a plurality of data detection techniques is selected. The selecting is based on at least one of a spatial stream, a symbol, and a carrier frequency associated with the given sample. The selected data detection, technique is used to detect data of the given sample.
