A wireless communication sniffer including: a packet identification module; a channel modeler; single-channel and multi-channel equalization matrix calculators; and an equalizer. The packet identification module identifies a packet as single-user (SU) or multi-user (MU). The channel modeler models the communication channel for the packet as either a set of single-channel or multi-channel parameters responsive to the SU and MU packet identification. The single-channel equalization matrix calculator calculates a single-channel equalization matrix using the set of single-channel parameters, responsive to an SU identification. The multi-channel equalization matrix calculator calculates a multi-channel equalization matrix using the set of multi-channel parameters, responsive to an MU identification. The equalizer equalizes the received communication packet utilizing the single-channel or multi-channel equalization matrix responsive to the SU or MU packet identification respectively.
