The paper presents a simulation analysis on filter bank multicarrier (FBMC) system with a bank of Mirabbasi-Martin window
filter. The Multicarrier modulation system has been introduced as the most suitable technique in the mobile communication
system due to its effectiveness in channels with multipath propagation. Cyclic Prefix Orthogonal Frequency division
Multiplexing (CP-OFDM) is the dominant multicarrier modulation technique, which achieves high performance in the long
term evolution system. However, in some applications such as cognitive radios and the uplink of the multicarrier system where
a group of subcarriers is specified to each user, CP-OFDM may be an unfavorable choice. In this paper we focus on proving
that FBMC transmultiplexer system provides improved performance with a bank of Mirabbasi-Martin window of filter length
is six times greater than the number of the subchannel. The filter length is chosen after simulation results of the overlapping
factor effect on the proposed filter. This value of the overlapping factor leads to fast falling off rate of the side lobes and good
stopband attenuation with smaller leakage factor. The proposed system can effectively reduce the drawbacks of Cyclic Prefix
Orthogonal Frequency Multiplexing. It has been numerically simulated to confirm that the proposed scheme results actually
improve the spectrum efficiency, orthogonality and spectrum containment making FBMC a suitable candidate for high speed
data transfer using Multicarrier Modulation. |
