WebClipping and filtering is the conventional method, including hard clipping and low-pass filtering. As shown in the above figure, clipping can cause sharp corners in a clipped signal, which leads to an unwanted out-of-band emission(increased ACP). WebIn the proposed method, first, the clipping noise other than the clipped signal is filtered; second, the filtering coefficients for the clipping noises in the data-plus-pilot region and guard region are set to be different values to achieve good tradeoff between PAPR and bit error rate (BER) performance.
