Claim:
1. A two-layer decoding method in a wireless local area network (“WLAN”) comprising: receiving a pair of overlapping packets at a network element in the WLAN transmitted concurrently from multiple users; communicating the pair of overlapping packets to a physical layer decoding unit comprising a multi-user decoding (“MUD”) decoder and a physical layer network coding (“PNC”) decoder, wherein the MUD decoder is adapted to attempt to decode each individual packet of the pair of overlapping packets, and the PNC decoder is adapted to attempt to decode a network-coded packet derived from the pair of overlapping packets transmitted from the multiple users and received at the network element; decoding a first packet of the pair of overlapping packets using physical-layer bridging when only a second packet of the pair of overlapping packets and the network-coded packet are decoded; and attempting to recover each of the pair of packets based on results obtained from the physical layer decoding unit.
