Abstract

An accurate model developed to analyze the effects of clipping for a Gaussian signal with an arbitrary spectrum is presented. The model provides information on the reduction of the signal level, the total noise power due to clipping and the spectral properties of the noise. The method is applied to a discrete multitone (DMT) transmission system with parameters that are applicable for the asymmetric digital subscriber line (ADSL) technology. System calculations given to illustrate this approach show a 5 dB improvement in the signal-to-noise (SNR) ratio compared to previous work using an approximate analysis
