Abstract
Enhanced stomp-and-restart techniques are provided. At a plurality of antennas of a wireless communication device, energy is received in a channel in which one or more frames may be transmitted to the wireless communication device from any one of a plurality of other wireless communication devices. A first frame is acquired from the received energy. Channel state information is computed for the first frame and the channel state information associated with the first frame is stored. Interference suppression parameters are computed for the first frame from the channel state information. It is determined whether a stronger second frame is being received by the wireless communication device. The received energy associated with the first frame is nulled-out using the interference suppression parameters when the stronger second frame is determined to be received so that start-of-packet processing and decoding is performed on the stronger second frame.
