Abstract:
1. A communication station that uses a plurality of antennas for transmission of orthogonal frequency division multiplexed (OFDM) symbols, the communication station comprising: an interleaver to interleave a block of encoded bits of an associated input bit stream for use in generating an output bit stream having a desired code rate; circuitry to modulate the bits of the output bit stream to generate complex-valued modulation symbols; circuitry to map the modulation symbols, on a per-symbol basis, for transmit diversity and space-frequency interleaving (SFI) to multiple antennas and OFDM tones; circuitry to cyclically shift the mapped modulation elements; circuitry to provide the cyclically-shifted modulation symbols for transmission by an associated one of the antennas; and circuitry to add a cyclic prefix to the modulation symbols prior to transmission.
