Comparative Study of WiMAX and LTE

Abstract

The Worldwide interoperability for microwave access (WiMAX) based on IEEE 802.16 and Long Term Evolution (LTE),are the most emerging broadband wireless technologies and is viable alternative to traditional wired broadband techniques due to its high resource utilization, easy implementation and low cost. A simulator for the WiMAX and LTE physical layer is presented in this paper. The main objective of this paper is to analyze and compare the performance of WiMAX and LTE physical layer under different modulation schemes based on SNR and BER results are presented with different digital modulation schemes in AWGN channel.
