Abstract:
ABSTRACT Numerous objectives motivate the current research on Wavelet Packet Modulation (WPM). Firstly, the characteristic of a multicarrier modulated signal is directly dependent on the set of waveforms of which it uses. Hence, its sensitivity to non-linear amplifiers, multipath channel distortion or synchronization error might give better values than an OFDM signal. Moreover, the greatest advantage of WPM lies in its flexibility. The wavelet packet signals overlap in both, time and frequency domain. Due to time overlapping, WPM systems don’t use a cyclic prefix (CP) that is commonly used in OFDM systems. This enhances the bandwidth efficiency compared to conventional OFDM systems. In this research paper, a thorough study is based on the mobile channel environment and the Bit Error Rate (BER) over signal to noise ratio performance comparison between the OFDM mobile communication system and the WPM mobile communication system are analyze. The study is simulated over an AWGN channel, multipath fading channels (time variant, time invariant), and BER performance of OFDM for various constellation points, BER performance of Wavelet families. Keywords: Bit error rate (BER), Mobile channel (MC), Orthogonal Frequency Division Multiplexing (OFDM), Quadurature amplitude modulation (QAM), Wavelet Packet Modulation (WPM).
