Abstract :
We consider an IFFT-based technique for reducing the peak-to-average power ratio (PAPR) of an orthogonal frequency division multiplexing (OFDM) signal. The intermediate signals in a radix decimation-in-time (DIT) algorithm is used for subblock partitioning in the partial transmit sequence (PTS) technique. We present a new subblocking technique which significantly reduces the computational complexity while providing PAPR reduction comparable to that with ordinary PTS.
