Abstract: The present disclosure describes apparatuses and methods of interference cancellation for receivers with multiple antennas. In some aspects, an interference packet transmitted by an interfering device of a wireless environment is received via multiple antennas of a device. Based on the interference packet, an interference channel that describes interference in the wireless environment is estimated. The device then receives an intended packet through the wireless environment in which the interfering device is operating. At least a portion of interference received with the intended packet, such as interference caused by other interfering packets, is cancelled using the interference channel. By so doing, a receiver may reduce effects of interfering packets or signals of the wireless environment to improve receive performance (e.g., bit-error rate) for packets that are intended for reception by the device.
