| 摘要 |
An apparatus and method for reducing peak-to-average power ratio (PAPR) in orthogonal frequency division multiplex (OFDM) comprising forming a plurality of OFDM frequency domain subcarriers; mapping the plurality of OFDM frequency domain subcarriers into a plurality of subset subcarriers; converting the plurality of subset subcarriers into a plurality of time domain subwaveforms; recombining the plurality of time domain subwaveforms into two or more time domain combined signals with low Peak-to-Average Power Ratio (PAPR); and frequency upconverting the two or more time domain combined signals to obtain a transmit signal.
