1. A wireless transmitter comprising:

  • tone group precoding matrix blocks having inputs coupled to outputs of bit allocation blocks and having outputs, the tone group precoding matrix blocks distributing signal energy across the tone groups for each of the multiple data streams to distribute the data bits across multiple tones;

    antenna precoding matrix blocks having inputs coupled to the outputs of the tone group precoding matrix blocks and having outputs, the antenna precoding matrix blocks being applied to the tones; and

    inverse fast Fourier Transform and parallel to serial blocks having inputs coupled to the outputs of the antenna precoding matrix blocks.
