Abstract
Certain aspects of the present disclosure provide techniques for peak to average power ratio (PAPR) reduction for orthogonal frequency division multiplexing (OFDM). An example method, performed at a transmitter, includes generating a plurality of orthogonal frequency division multiplexed (OFDM) symbols, based on a constellation associated with a modulation scheme, adjusting a phase of at least one of the OFDM symbols based on at least one parameter that depends on a non-integer multiple of a phase distance between two points on the constellation, generating a Discrete Fourier Transform spread OFDM (DFT-s-OFDM) waveform based on the OFDM symbols after the adjustment, and transmitting the DFT-s-OFDM waveform to a receiver.
