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

Claim 0:
1. 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:
add a set of redundant subcarriers to a set of data subcarriers to be transmitted in a unique-word orthogonal frequency division multiplexing (UW-OFDM) waveform, wherein the set of redundant subcarriers is based at least on multiple head samples and multiple tail samples to be included in the UW-OFDM waveform;
interleave, based on a permutation matrix, the set of redundant subcarriers with the set of data subcarriers to generate a permutation of subcarriers;
map the permutation of subcarriers as input to an inverse fast Fourier transform (IFFT); and
generate the UW-OFDM waveform based on output of the IFFT.
