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.
