KEY PARAMETERS INFLUENCE ON WAVELET BASED OFDM SYSTEMS
In this paper, we investigate the use of orthogonal wavelet basis functions as an alternative to multicarrier systems based on fast Fourier transform. The influence of the key parameters such as the wavelet decomposition level, the wavelet basis family and the filter order on the receiver detection performance is studied in comparison to the conventional orthogonal frequency division multiplexing. Numerical results conducted over both AWGN and multipath fading channels show that wavelet based OFDM outperforms conventional OFDM in multipath channels in terms of bit error rate. This improvement is examined in the face of different wavelet filter orders and decomposition levels.
