Abstract

One of the important schemes for modern communication is Filter Bank Multi-Carrier with Offset Quadrature Amplitude Modulation (FBMC/ OQAM), as it provides better spectral efficiency with small inter-symbol and inter-carrier interference specially in data fusion platforms.  Unfortunately, the design of filter banks in FBMC is difficult and complex to achieve the requirement due to complexity of handling the data fusion issues.  This paper presents a proposed method to design a uniform and nonuniform filter banks using a data fusion optimization technique.  The design process represented as an objective function describes the amplitude in the stop band, and the goal is to minimize the objective function.  Different examples are provided to illustrate the efficiency of the proposed design method.
