MODELING AND ANALYZING THE BER PERFORMANCE OF OFDM- MIMO SYSTEM WITH 16-QAM USING OSTBC FOR WIRELESS COMMUNICATION BASED ON MATLAB
Journal Title: International Journal of Electrical and Electronics Engineering Research (IJEEER) - Year 2017, Vol 7, Issue 2
Abstract
In this paper we have investigated the performance of OFDM-MIMO wireless system. The main objective of this paper is to introduce the basic structure of OFDM and MIMO, including the basic implementation of a MIMO model using OSTBC scheme, the effectiveness of introducing encoders and interleavers in a OFDM-MIMO system, the transmitter and receiver modeling of OFDM, and hence constructing a simple OFDM-MIMO wireless communication system in WLAN and Wi-Fi context with 16-QAM modulation composed of transmitter, channel, receiver, and so on. The system performance is simulated by using the software MATLAB. All the models are being studied for different configurations, that is, for different number of antennas at the transmitter and receiver of the communication system. The results are obtained and compared in terms of Bit Error Rate (BER), Throughput and Bandwidth.
