Analysis of Daubechies 2 Wavelet in WPM System for Adhoc Network

Abstract

Wavelet packet modulation (WPM) has been proven as one of the multi-carrier modulation (MCM) techniques with improved features and improved characteristics. To make the WPM system more efficient, different techniques were used. In this research work, WPM system is designed by using db2 wavelet on three different modulation schemes BPSK, QPSK and 16-PSK. Further, each modulation scheme was tested under three different channel conditions, i.e. AWGN, Rayleigh and Rician. After successfully experimentation, it has been concluded that the WPM system with QPSK modulation under AWGN channel condition using Daubechies (db2) wavelet gives a better performance for adhoc network parameters like BER, throughput and energy consumption.
