Effect of Block Size on BER Performance of Inverse Filtering Based MIMO FBMC

Abstract Filter bank multicarrier (FBMC) is a novel next generation data transfer technique. FBMC has large number of benefits over conventional OFDM techniques. The FBMC scheme suffers from imaginary interference thus degrades the bit error rate (BER) performance at the receiver. In recent past ICI free Alamouti-coded FBMC, frame and block repetition schemes for BER improvement are discussed. However, in the analysis various interfering terms are neglected. In this work to reduce inter carrier interference (ICI) and inter symbol interference (ISI) concept of inverse filtering is applied without neglecting other interfering terms and mathematical equations are derived and BER is evaluated. The simulation results are presented and compared with state of art technologies and it has been found that the proposed scheme is better in comparison to to state of art technologies.
