Tail cancelation and addition of unique word for orthogonal frequency division multiplexing

摘要

A wireless transmit/receive unit (WTRU) may generate a first signal that utilizes a tail suppression signal generated from data and utilizes a first unique word. Elements of the data and the first signal may be mapped to one or more discrete Fourier transform spread (DFT-S) functions. An inverse DFT on symbols generated by the one or more DFT-S functions may be performed to generate a second signal for transmission.
