Performance Improvement of MIMO-FBMC Systems Using Different Diversity Combining Schemes Through AWGN and Rayleigh Channels
Diverse methodologies of Diversity combining schemes are used for performance improvements of Filter Bank Multicarrier (FBMC) by using Additive White Gaussian Noise and Rayleigh channels. These diversity combining schemes are Maximum Ratio combining and Selection Combining. The proposed schemes are implemented by using different channels of MIMO methodology, which results in high order diversity. This system simulation includes varying number of receiving antennas to analyzes the performance over AWGN and Rayleigh channel. The aim of the proposed schemes is to improve bit error rate (BER) performance with using two different diversity combining schemes. It observed through MATLAB simulations that the proposed schemes provides evident performance improvements.
