For wireless communication system high bit rate and low bit error rate is required. Research towards the growing demands and to fulfill the requirements of high data rates, multiple channel bandwidths (1.25-20MHz) and spectral efficiency, Long Term Evolution (LTE) is an area of research interest for next generation of wireless communication. Orthogonal Frequency Division Multiplexing (OFDM) is selected as the basis of LTE physical layer. This paper presents the performance of OFDM UMTS based LTE system where minimum BER is measured for different modulators.
