Classification: CPC H | IPC H

Claim 25:
26. A method for wireless communications, comprising:
receiving a unique-word orthogonal frequency division multiplexing (UW-OFDM) waveform;
generating a mapping of subcarriers by performing a fast Fourier transform (FFT) of the UW-OFDM waveform;
demapping, from the mapping of subcarriers, a permutation of a set of redundant subcarriers and a set of data subcarriers, wherein the set of redundant subcarriers is based at least on multiple head samples and multiple tail samples included in the UW-OFDM waveform;
separating, based on a permutation matrix, the permutation of the set of redundant subcarriers and the set of data subcarriers; and
processing the set of data subcarriers to obtain data transmitted in the UW-OFDM waveform.
