ABSTRACT:
A multicarrier transmitter performs bit-interleaving suitable for transmitting more than one spatial stream over a multicarrier communication channel. The multicarrier transmitter may include a bit-grouping shifter to shift QAM symbol-bit groupings of a spatial stream among subcarriers of the multicarrier communication signal, and a bit-position permuter to rotate bits among bit positions within subgroupings of the QAM symbol-bit groupings of the second spatial stream.
