Abstract: A receiver (200) for receiving for receiving encoded data transmitted simultaneously as a plurality of M different sequences of transmitted symbols from different transmit antennas using a plurality of m modulation levels, where M and m are integers and each of the transmitted symbols represents a plurality of bits of the encoded data, comprises a demodulator (210) arranged to provide N received symbol combinations by receiving at a plurality of N receive antennas (202, 204), where N is an integer, the plurality of M different sequences of transmitted symbols, wherein each received symbol combination comprises M simultaneously received ones of the transmitted symbols. An equalizer (230) is arranged to generate from the N received symbol combinations M pre-processed signals by performing interference cancellation, in which interference cancellation a different symbol of the respective received symbol combination is a wanted signal and the other symbols of the respective received symbol combination are interfering signals. The equalizer (230) is also arranged to generate from each of the M pre-processed signals a list of up to m initial candidate symbol combinations by, for each of the up to m initial candidate symbol combinations, selecting a first initial symbol indicative of a different one of the m modulation levels and selecting M−1 further initial symbols. The equalizer (230) is further arranged to generate from the lists of initial candidate symbol combinations an initial estimate of the transmitted symbols. A decoder (260) is arranged to decode bits represented by the initial estimate of the transmitted symbols.
