Abstract

yesThis paper investigates the performance of wavelet OFDM signals\ud over a wireless communications link. The scheme is shown to be generally\ud similar to Fourier based OFDM, but with some additional features, and\ud improved characteristics. The sensitivity of both schemes to the nonlinear\ud amplification in the transmitter is compared by monitoring the time domain\ud output data and the adjacent channel power ratio (ACPR) performance.The Institute for Computer Sciences,\ud Social Informatics and Telecommunications Engineerin
