We consider scenarios such as machine-to-cellular communications, where a low-cost transmitter communicates with a high-quality receiver. Then, digital pre-distortion of the non-linear power amplifier may be too expensive. In order to investigate the feasibility of receiver-side compensation of the transmitter RF impairments, we study estimation of the clipping level in OFDM systems. Both blind and pilot based schemes are proposed and numerical evaluations show that iterative decoding can be done using the estimated clipping level without any significant performance loss.
