1. A method, comprising:
receiving, by a first station (STA) of a plurality of STAs from an access point (AP), a multiplexed bit stream of a multi-user-multiple input multiple output (MU-MIMO) signal comprising an interleaved plurality of encoded bit streams, modulated 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 the first STA 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; and
demodulating, by the first STA, the OFDMA symbol,
wherein the first STA is associated with a first subcarrier and the second STA is associated with a different subcarrier.
