Assignee: QUALCOMM INCORPORATED
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 14:
15. An apparatus for wireless communication, comprising:
a transceiver;
a memory configured to store instructions;
one or more processors communicatively coupled with the memory and the transceiver, wherein the one or more processors are configured to:
receive a unique-word orthogonal frequency division multiplexing (UW-OFDM) waveform;
generate a mapping of subcarriers by performing a fast Fourier transform (FFT) of the UW-OFDM waveform;
demap, 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;
separate, based on a permutation matrix, the permutation of the set of redundant subcarriers and the set of data subcarriers; and
process the set of data subcarriers to obtain data transmitted in the UW-OFDM waveform.
