1. A wireless communication device comprising:

  • a first encoder that encodes a data stream based on an error-control code to produce encoded symbols;

    an interleaver that interleaves the encoded symbols to produce interleaved symbols;

    a constellation mapper that maps the interleaved symbols to produce a stream of information bearing symbols selected from a constellation having a finite alphabet;

    ana second encoder that applies a linear transformation to athe stream of information bearing symbols selected from athe constellation having athe finite alphabet to produce a stream of precoded symbols that are complex numbers and that are not restricted by the constellation of the information bearing symbols; and

    a modulator to produce an output waveform in accordance with the stream of precoded symbols for transmission through a wireless channel.
