PERFORMANCE ANALYSIS OF FILTER BANK MULTICARRIER IN RAYLEIGH FADING ENVIRONMENT

Multicarrier techniques are gaining more attention to provide larger data rate in future radio communication system. Filter bank multicarrier (FBMC) is a modulation technique which overcomes the various limitations of already existing techniques like PAPR problem in OFDM, intersymbol interference etc. FBMC is a derivative of OFDM. Basically, the FBMC is also a modulation and multiplexing multicarrier scheme and it is used to reduce the inter-channel interference in LTE, which is the major problem in the wireless networks and increases the bandwidth efficiency using filter banks to eliminate the interference of the subcarriers instead of using guard interval between two or more subcarriers. To deal with 5G system new modulation techniques are required such as FBMC. In this paper, we check the performance evaluation of FBMC and compare it to OFDM based scheme. We also analyze the throughput of FBMC in Rayleigh fading environment using MATLAB
