摘要: A transmitter and method for processing a digitally modulated communication signal, which may reduce peak-to-average-power-ratio (PAPR) while maintaining acceptable error rates is disclosed. After subcarrier mapping, first digital representation of the signal upsampled into second representation, transformed time domain representation. Samples whose magnitudes exceed magnitude limit are limited to that produce The third frequency downsampled fourth In addition in-band subcarriers, some out-of-band subcarriers adjacent band preserved remaining eliminated fifth then converted an analog be transmitted.
