Claim 8:
9. An access point (AP) comprising:
at least one processor; and
a transceiver,
the at least one processor and the transceiver configured to:
receive a plurality of encoded bit streams, wherein each of the plurality of encoded bit streams is associated with one of a plurality of subcarricr users stations (STAs), wherein each of the plurality of STAs is associated with different subcarriers; and
transmit a multiplexed bit stream for multi-user-multiple input multiple output (MU-MIMO) signal by interleaving the plurality of encoded bit streams and modulating the interleaved plurality of encoded bit streams such that a modulated Orthogonal Frequency-Division Multiple Access (OFDMA) symbol from the interleaved plurality of encoded bit streams includes a plurality of bits from an encoded bit stream associated with a first STA of the plurality of STAs and a plurality of bits from an encoded bit stream associated with a second STA of the plurality of STAs, wherein adjacent bits of the interleaved plurality of encoded bit streams are mapped onto non-adjacent subcarriers of the modulated OFDMA symbol.
