Abstract:
1. A system comprising: a number M receive antennas configured to receive a number N transmitted signals associated with respective data streams; a number N beamformers connected to the M receive antennas, configured to combine signals coming from the antennas, wherein M is greater than N, and wherein M and N are integers a baseband module coupled to the N beamformers configured to apply at least one multiple input multiple output (MIMO) receiving scheme to the combined signals; and a control module configured to: assign each of K receive antennas in each beamformer with a phase/gain that maximizes a received power of at least one of the data streams; wherein K is an integer; compare overall performance of mapping configuration which map between the beamformers and the data streams; and select the mapping configuration which results in higher signal to interference plus noise (SINR) measured at the baseband module, wherein the received power is computed via pre-coding weight and channel estimation through each of the K receive antennas.
