Clipping noise-based tone injection for PAPR reduction in OFDM systems
2013
2013 IEEE International Conference on Communications (ICC)
Tone injection (TI) mitigates the high peak-toaverage power ratio problem without incurring data rate loss or extra side information. However, optimal TI requires an exhaustive search over all possible constellations, which is a hard optimization problem. In this paper, a novel TI scheme that uses the clipping noise to find the optimal equivalent constellations is proposed. By minimizing the mean error of the clipping noise and possible constellation points, the proposed scheme easily
