Window functions have been successfully used in various areas such as filtering, beam forming and multirate signal processing. Due to available closed form expressions, the role of windows is economical. One of the key applications is the design of FIR filters. These filters are used in decimators and interpolators which are the basic building blocks for any multirate system and filterbank. In present scenario, a system with an improved performance, better quality, little error is the prime requirement. With this objective FIR multirate filters are designed using window functions. These...

Recently, Multicarrier Modulation find wide application in many areas of communication Engineering like IEEE 802.11a/g, IEEE 802.16e,IEEE 802.20, DVD, DAB, ADSL and VDSL, etc. The orthogonal property provides optimum loading of the channel spectrum with effective suppression of Interferences parameters, i.e., ICI and ISI. The TMUX is the major component of MCM system. It works like a dual of Filter bank and can be efficiently realized using basic properties of Multirate signal processing. The CMFB is one of the computationally efficient techniques for the implementation of filter bank in NPR...
