The upcoming wireless communication systems require optimal usage of the bandwidth provided. As the technology is getting advanced, the data traffic is going to increase so there is difficulty in utilizing the spectrum provided if the conventional physical layer technique called as Orthogonal Frequency Division Multiplex (OFDM) is used, because it needs cyclic prefix. There is also difficulty while Multiple- input and Multiple-output (MIMO) is to be used. This paper develops a method prior to the OFDM which provides more spectral efficiency and characterized for the well-localized spectrum, this technique is called as Filter Bank Multi-Carrier (FBMC).To show that FBMC is an well-organized modulation scheme than the OFDM, this paper compares the responses and density estimates of FBMC and OFDM through the results simulated using MATLAB.
