1. A method of transmission of a symbol stream, comprising:

  • (a) providing P transmit antennas where P is an integer greater than or equal to 3;

    (b) splitting a data stream into M symbol streams to transmit from the P antennas through communication channels where M is an integer greater than or equal to 2; and

    (c) multiplying the symbol streams by a rectangular matrix that corresponds to a diagonal M×

    M block matrix of (P/M)×

    1 vectors where each (P/M)×

    1 vector corresponds to weights for a symbol stream of the M symbol streams.
