Abstract

Three versions of Clipping & Filtering (CF) and just controlled clipping without filtering are compared using extensive simulations. The comparison is performed according to minimum BER criteria while taking into account the spectral mask constraint. The clipping, no matter how implemented, introduces in-band distortions; therefore we will name it 'distortion-yes' technique to reduce PAPR. It is obtained that CF gives non-significant better performance than controlled clipping for spectral masks requiring very high spectral purity. However, for spectral masks of practical systems, such as WiMAX, the performance of CF (or its iterative version) and just clipping are exactly the same. It may be concluded that for such cases there is no justification for the use of CF or Iterative CF.
