Filter bank Multi Carrier (FBMC) modulation is one of the design technique proposed has attracted considerable interest in case of 5G. Reducing subcarrier leakage is a prime issue for high data rate with less subcarrier space. FBMC provides small intermediate leakage comparing to that of orthogonal frequency division multiplexing (OFDM) to enable high data rate communication with less subcarrier space. The prototype filter and the filter bank design is one of the important problems under FBMC. This article proposes a new prototype filter design and filter bank design for the FBMC system by combination of weighted Hermite Polynomials based prototype and cosine modulation. The performance in terms of bit-error-rate (BER) of the proposed system is analyzed on AWGN, Rayleigh and Rician fading channel. The BER result proves that the proposed filter design achieves better performance comparing to that of the earlier techniques.
