Performance Analysis of Coded Reception in Multipath Fading Channels with Wavelet Packet Based OFDM Transmission

Abstract:

Abstract. Radio propagation on wireless channels depends on many static and dynamic factors like, buildings, trees, mountains, frequency of operation, velocity of mobile stations and interfering sources. Mathematical models for channel are considered for various communication functions like, predicting radio coverage, estimation of interferences from various sources, estimating the characteristics of an alternate transmitter and receiver, achievable data rates and for determining the location for wireless infrastructure. Signal propagation in fading channels cause degradation of signal QoS. OFDM is often used to mitigate fading effects in wireless channels; the paper describes the disadvantage of OFDM and provides a wavelet based solution to surmount it. The paper also investigates the BER vs. SNR performance of modified OFDM using wavelet packet in Rayleigh and Rician Channels and the results are compared with conventional OFDM.
