Performance Comparison of Wavelet Packet Modulation and OFDM over Mobile Communication Channel
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 2, Issue 6
Abstract
ficient solution for mobile communication. Wavelet Packet based Multi-Carrier Modulation (WPMCM) offers an alternative to the well-established OFDM as an efficient multicarrier modulation technique. Wavelet Packet Modulation (WPM) is a new type of modulation for transmission of multicarrier signal on mobile channel that uses orthogonal wavelet bases other than sine functions. It has strong advantage of being generic transmission scheme whose actual characteristics can be widely customized to fulfill several requirements and constraints of advanced mobile communication systems. In this paper, a detailed study is given on the mobile channel environment and the Bit Error Rate (BER) performance comparison between the OFDM mobile communication system and the WPM mobile communication system are analyzed. The analysis is simulated over an AWGN channel, and other Multipath fading channels like time invariant frequency selective channel and time variant frequency selective channel.
