Performance evolution of downlink mimo in LTE technology

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. 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 project mainly focuses on design of a LTE DL (downlink) inspired channel simulator using the AWGN and fading channel model, here OFDMA is used as a multiple access scheme. The performance of noise and interference in AWGN channel and fading channel at LTE DL is measured and compared to obtain less noisy channel. Both lower and higher order modulation schemes are used in LTE DL. The parameters used for comparison in AWGN channel and fading channel are BER (Bit Error Rate) and Eb/No (db).The proposed work is about to reduce the noise in AWGN channel and fading channel.
