Iterative Compensation for Clipping Noise in Spatial Modulation OFDM Systems.

Clipping is an effective technique to adjust the peak-to-average power ratio (PAPR) of spatial modulation (SM) orthogonal frequency-division multiplexing (OFDM) systems. In this paper, an iterative soft compensation method is proposed for mitigating the effect of the clipping noise. In the proposed method, the sparsity and relativity of all transmit antennas are exploited, and the mean and power o...
