What is OFDM Signal PAPR Reduction Techniques about?

The document summarizes techniques to reduce peak-to-average power ratio (PAPR) in orthogonal frequency division multiplexing (OFDM) signals. It describes clipping, selective mapping (SLM), and partial transmit sequence (PTS) techniques. Clipping works by limiting signal peaks but causes bit error rate degradation and out-of-band radiation. SLM generates multiple candidate signals and selects the one with the lowest PAPR, increasing complexity. PTS divides the signal into blocks, applies phase factors to cr
