Design of Digital Filter for Multistandard Wireless Transceivers
A digital decimation filter is designed for delta - sigma analog to digital converter. The designed filter has a multi-stage structure which is comprised of a stage CIC filter, two stage half - band filters and a stage compensation filter. Now-a-days in wireless and audio application the use of efficient digital filter is increasing because of the speed of conversion, fast performance. So the filters are designed to match the requirements. The demand for new telecommunication services requiring higher capacities. A decimation filter design tool for wireless communication standards consisting of GSM and WiMAX is developed in using GUIDE environment for visual analysis. The user can select a required wireless communication standard and obtain the corresponding multistage decimation filter implementation using the toolbox.
