1. A method of precoding vectors in a communication system, the method comprising:

  • receiving an information symbol vector u and a channel matrix H;

    calculating a transmit vector x using the information symbol vector u and the channel matrix H;

    perturbing an entry of the information symbol vector u;

    determining an energy value of the transmit vector, wherein if the energy value of the transmit vector x decreased, perturbing another entry of the information symbol vector u, and if the energy value of the transmit vector x did not decrease, transmitting the transmit vector x,wherein the method comprises perturbing one entry of the information symbol vector u at a time.
