Effect of Various Parameters on BER of Wireless Communication System

purpose of this paper presents 802.11b PHY simulation model BER. In this model various parameters are given like data rate, packet size, various wireless channel number and channel type. So we perform the model for fixed channel AWGN, data rate1mbps, 2mbps 5.5 mbps and 11 mbps and Packet size varies from 1-4095. It's give various BER graph for various channel number. Key Words—Transmission, IEEE 802.11b, PHY, Simulink, BER
