ABSTRACT:
A wireless communication device corrects data transmission errors caused by the simultaneous transmission of multiple streams of data in a Multiple-Input Multiple-Output (MIMO) network. The wireless communication device corrects data transmission errors by removing the signal contribution associated with one or more received signal components from a corresponding received composite signal, thus allowing the remaining components to be decoded relatively free from the signal contribution of the removed components. In one embodiment, the wireless communication device comprises a plurality of antennas and a baseband processor. The antennas are configured to receive a composite signal having a plurality of received signal components. The baseband processor is configured to obtain decoding quality metrics for individual ones of the received signal components, form regenerated received signal components for the received signal components having satisfactory decoding quality metrics, and remove the regenerated received signal components from the received composite signal.
