Wavelet transformation method to allocate the DVB-T signals peaks

Abstract

Terrestrial digital video broadcasting (DVB-T) is considered as one of the main two popular broadcasting standards, which facilitates the transmission of digital television in handheld receivers. In this work, a comparison will be held on the physical layer level in order to enhance the wireless systems' performance. It is attained by exploiting a recently published work that is based on the wavelets entropy and a new proposition that is based on a special averaging technique. Those two propositions have been used to tackle the peak-to-average power ratio (PAPR) problem that is found in the used orthogonal frequency division multiplexing (OFDM) technique. This comparison asset from BER curves and CCDF curves in order to distinguish between them. A MATLAB simulation has been run in order to validate the numerical achieved results of the proposed work. At the same bandwidth occupancy of the speaker verification-based systems, the proposed technique shows additional enhancement in both of CCDF and BER curves...
