Performance Evaluation of LTE OFDM System Using an Adaptive Modulation Scheme in Indoor and Outdoor Environment

The growing requirements of mobile broad band services like MIMO, combined with OFDM involved in 4g wireless networks were met by Long Term Evolution (LTE).OFDM is used in communication systems to provide high data rates, and is more immune to intercarrier interference, and intersymbol interference. OFDM has become the core of LTE system. In this paper the performance of the system is evaluated in terms of signal to noise ratio and spectral efficiency and simulation of the system is carried out using MATLAB programming in LTEs indoor and outdoor environment.The simulation is carried out for different bandwidths and a comparison plot is shown for SNR(db) Vs spectral efficiency(bits/Hz).
