Abstract
Peak-to-average power ratio (PAR) reduction is an effective way to increase the power efficiency and decrease distortion noise in orthogonal frequency division multiplexing (OFDM) systems. Many PAR reduction schemes have been proposed, but few incorporate symbol-wise channel estimation and none accommodate per symbol synchronization. In this paper we present joint synchronization pilot sequence (JSPS) selected mapping (SLM), which is a joint PAR reduction and synchronization scheme. In harsh peak-limited channels we show that JSPS-SLM can achieve large bit error rate (BER) performance gains.
