Abstract
A radio communication system comprises a communication channel between a transmitter () comprising a plurality of antennas () and a receiver () comprising at least one antenna. The communication channel is wideband and comprises a plurality of paths, and the transmitter comprises means for splitting data for transmission into a plurality of sub-streams. The receiver comprises fewer antennas than the number of transmitted sub-streams and sampling means for determining at least as many substantially uncorrelated received signal samples as the number of sub-streams. In one embodiment, transmissions on the channel employ code division techniques and the sampling means comprises a Rake receiver. In another embodiment a maximum likelihood technique is used to generate sufficient samples. By means of the present invention a receiver for use in a Multiple Input Multiple Output (MIMO) communication system may comprise fewer antennas than the number of sub-streams, thereby enabling smaller terminals.
