1. A device comprising:

  • circuitry configured tospread symbols with orthogonal codes into spread signals having a predetermined number of bits,modify an amplitude of the spread signals via layer coefficients, andmultiplex the amplitude modified spread signals into a layered transmit signal; and

    a communication interface configured to transmit the layered transmit signal, wherein the circuitry is configured todetermine the layer coefficients based on a coefficient difference factor that is less than one, anddetermine a highest layer coefficient to be greater than a sum of a plurality of remaining lower layer coefficients.
