MODELING AND PERFORMANCE EVALUATION OF QAM-OFDM SYSTEM WITH DIFFERENT TRANSMISSION SCHEMES
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 2015, Vol 4, Issue 1
Abstract
In wireless communication system, the receiver side Bit error ratio (BER) strongly affected by channel error, interference, distortion, synchronization error and wireless multipath fading channels. Multiple-input and multipleoutput, (MIMO ) is the use of multiple antennas at both the end in wireless communication to improve Bit error ratio (BER) performance. In this paper, has been performed evalution of QAM-OFDM with transmission schemes. This model is used for performance evaluation of the OFDM with QAM modulation schemes and fading channel. The throughput and packet error rate are used to evaluate the performance of MAC layer with the change in physical layer parameter, the using FEC code. The results has been shown in the paper for the simulation in various condition.
