Abstract

In this paper, a novel orthogonal frequency division multiplexing (OFDM) system based on dual–tree complex wavelet transform (DT-CWT), is presented. In the proposed system, the DT-CWT is used to replace the fast Fourier transform (FFT) in the conventional OFDM. This results in considerable improvement in terms of bit error rate (BER) over not only the conventional OFDM but also to the wavelet packet modulation (WPM) based OFDM system. Moreover, the proposed system achieves better peak–to–average power ratio (PAPR) performance at acceptable increase in computational complexity. The complementary cumulative distribution function of PAPR for the proposed system shows 3 dB improvement over the conventional and the WPM based OFDM systems.
