Abstract:
A communication station uses a plurality of antennas for transmission of orthogonal frequency division multiplexed (OFDM) symbols. The communication station includes 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. The communication station also includes circuitry to modulate the bits of the output bit stream to generate complex-valued modulation symbols, circuitry to map the modulation symbols for transmit diversity to layers for each of the antennas based on a number of antennas used and to further map the modulation symbols for each antenna onto resource elements, 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.
