Abstract
Various embodiments of techniques related to interference cancellation in wireless OFDMA with MIMO spatial multiplexing are provided. In one aspect, a method receives wireless communication downlink signals from a first base station and a second base station. The method cancels interference of wireless downlink communications between the first base station and the communication device by the second base station by calculating an equalizer solution that orthogonalizes the downlink signals from the first and the second base stations.
