1. A digital processing system utilized in a transmitter that generates a transmission signal, the system comprising:

  • a first circuit that receives a discrete signal of complex data symbols, calculates a frequency response of the discrete signal, and outputs a first vector of length M;

    a second circuit that receives the vector of length M and generates a second vector of length N, wherein the second vector of length N includes elements of the first vector at positions corresponding to tones allocated to the transmitter; and

    a third circuit that receives the second vector and generates a digital time domain vector therefrom for transmission by the transmitter.
