Optimized Filter Design For Pr-Qmf Based Spread Spectrum Communications

Design of a Micro strip Quad-Band Band pass Filter for LTE Using Stub Loaded Resonators

A Quad-band bandpass filter for wireless RF devices is presented. The circuit is capable of serving multiple FDD and TDD bands of the 4G LTE standard. A microstrip transmission line is used to feed stepped impedance resonators for providing four bands in LTE spectrum. The proposed filter is simulated using IE3D simulator. The centre frequency and bandwidth of each passband can be controlled by ...

Development of Web GIS-Based VFSMOD System with Three Modules for Effective Vegetative Filter Strip Design

In recent years, Non-Point Source Pollution has been rising as a significant environmental issue. The sediment-laden water problem is causing serious impacts on river ecosystems not only in South Korea but also in most countries. The vegetative filter strip (VFS) has been thought to be one of the most effective methods to reduce the transport of sediment to down-gradient area. However, the effe...

Filter Banks in Digital Communications

Digital signal processing has played a key role in the development of telecommunication systems over the last two decades. In recent years digital filter banks have been occupying an increasingly important role in both wireless and wireline communication systems. In this paper we review some of these applications of filter banks with special emphasis on discrete multitone modulation which has h...
