Abstract
In this study, the authors propose an efficient peak-to-average power ratio (PAPR) reduction system for OFDM transmission based on tone reservation (TR). In this system, a novel cost function to jointly optimise the clipping level and the peak-cancelling signal is proposed. The obtained optimal clipping level can not only render the clipping noise to be well approximated by the reserved tones, but also be small enough to deeply suppress the peaks. In addition, a new cyclic method to optimise the peak-cancelling signal and the clipping level is presented with the insight that when optimising the reserved tone values, the time-domain signal to be thresholded itself depends on the peak-cancelling signal instead of being constant, as assumed by many other methods. Simulation results show that the proposed system significantly improves the PAPR reduction performance over the state-of-the-art clipping-based TR algorithms.Keywords
