Research towards meeting the higher demands for

higher data rates was the main reason for the birth of an

evolution technology towards the 4th generation mobile

communication systems. This evolution to the current 3rd

generation UMTS systems was given the name E-UTRA/UTRAN

Long Term Evolution (LTE) by the 3GPP. This paper analyzes

the requirements for this evolution and evaluates the

performance of the OFDM-LTE system under different

propagation impairments (AWGN and multipath fading

channels involving Pedestrian and Vehicular scenarios) in terms

of bit and symbol error rates (BER and SER) for different

modulation formats.
