Analysis And Modeling Of GSM/EDGE Mobile Communication System

In this study, Enhanced Data rate for GSM Evolution (EDGE) mobile communication system is analyzed and modeled assuming to operate in both Additive White Gaussian Noise (AWGN) channel and Rayleigh fading channel. A MATLAB software package is developed to simulate extensively the EDGE system. The system analysis takes into account channel coding, modulation type, interleaving and burst building, multipath channel effect, channel estimation, and detection process. The modeled system is simulated and tested for AWGN channel and 6-path of Rayleigh fading channel and the simulation results indicate clearly that the eye opening of the received signal decreases as the Signal to Noise Ratio SNR decreases and this effect is more pronounced in the presence of fading channel. It is also noted that, to obtain the same eye diagram for both transmitted and received signals, the SNR values needed at the receiver are 40 dB and 60 dB when the system is operating in AWGN channel and Rayleigh fading channel respectively.
