Claim Text:
1. A processor-based apparatus for generating wireless communications, the processor-based apparatus comprising: a first circuit configured to perform a Discrete Fourier Transform (DFT) on a discrete signal of complex data symbols to obtain a first frequency response vector of length M; a second circuit configured to perform an N-point Inverse DFT (IDFT) on a second frequency response vector of length N to obtain a vector of digital signal samples, wherein the second frequency response vector is generated from the first frequency response vector and the second frequency response vector has entries corresponding to one or more groups of tones allocated to the processor-based apparatus and zero value symbols corresponding to tones not allocated to the processor-based apparatus; and a third circuit configured to generate a low peak-to-average orthogonal frequency division multiplexing (OFDM) signal representing the vector of digital signal samples for transmission.
