- Abstract
- For orthogonal frequency division multiplexing (OFDM), we propose a new peak-to-average power ratio (PAPR) reduction scheme with low complexity based on time domain signal combining. The proposed scheme superposes an OFDM signal and its phase shifted cyclic delay signal to generate a signal candidate with lower PAPR. It is shown that the proposed scheme provides PAPR performance performance comparable to the conventional schemes for with lower complexity.
