LTE (Long Term Evolution) is the last step towards the 4th generation of radio technologies designed to increase the capacity and speed of cellular networks. Where at present current generation of cellular technology dominated by 3G (third generation), LTE is marked as 4G. The third generation partnership project (3GPP) currently work for developing the 3rd generation mobile and telecommunication system with a future 4th generation system. This thesis mainly focuses on design of a LTE DL (downlink) inspired channel simulator using the SUI 3 channel model, here OFDM uses as a multiple access scheme. The performance of SUI 3 channel at LTE DL is measured by comparing the AWGN limit.

In this thesis work, a simplified LTE downlink system was simulated using the SUI 3 channel model. The simulator was verified by comparing the simulated BER with the AWGN limit for the given modulation scheme. It is clear from the simulation that for BER = 0.01 there is SNR loss of 4 dB when using the SUI3 channel compared to the AWGN theoretical limit. This was expected since no coding or channel equalizer was implemented
