| 1. An apparatus comprising:
an interference processor operative to obtain input symbols for multiple antennas, to estimate interference due to a correctly
decoded packet received via at least one time-frequency block among a plurality of time-frequency blocks, and to subtract
the estimated interference from input symbols for the at least one time-frequency block to obtain interference-canceled symbols;
a spatial processor operative to perform receiver spatial processing on the interference-canceled symbols and provide detected
symbols for the at least one time-frequency block; and
a receive data processor operative to demodulate and decode detected symbols for at least one packet that overlaps at least
partially with the correctly decoded packet.
