Performance Analysis of an OFDM System for Different channel Models
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 11
Abstract
In today’s world depending on the requirements in the wireless communication, a system which provides high capacity and high performance and yields lower bit error rate (BER) value is preferred. Orthogonal frequency division multiplexing (OFDM) technique provides high spectral efficiency and transmits data using a number of subcarriers which are dependent on the principle of orthogonality. In this paper, the effect of various fading channels on BER is analyzed which gives the performance of OFDM system and the Doppler Effect on the Rayleigh fading channel is taken into account. Bit error rate among the considered fading channels is observed. With the help of MATLAB, the performance of the system is analyzed and the results are imparted.
