    Abstract: This research aims to design and implement of tree-structured multichannel filter banks using MATLAB. The multichannel filter banks analysis are evaluated by the Digital Signal Processing (DSP) techniques. The multi rate analysis is suitable for sampling rate reduction and sampling rate increase on the digital filter design. When increasing samplin... Show More

    Abstract: The paper presents the high date rate filter design for satellite communication using MATLAB. In this work, we considered only the numerical analysis for digital filter design based on the mathematical modeling of the filter design implementation. Result shows that operating frequency of IFIR filter is more than 5 times of that of IIR filter and w... Show More
