Methods for joint PAPR and spectral improvement of correlatively coded OFDM system

Abstract

Although correlative codes can significantly improve the spectral performance of the rectangularly pulsed orthogonal frequency-division multiplexing (OFDM) signals, they usually have high peak to average power ratio (PAPR) values. Two methods are proposed in this paper to reduce the PAPR values of the correlatively coded OFDM signals. First, a precoding… (More)
