GUI based decimation filter design tool for multi-standard wireless transceivers

The demand for new telecommunication services requiring higher capacities, data rates and different operating modes have motivated the development of new generation multi-standard wireless transceivers. A multi-standard design often involves extensive system level analysis and architectural partitioning, typically requiring extensive calculations. To expedite the handling of complicated design calculations, a GUI based design tool is proposed in this paper. In particular, multi-standard decimation filter design for six wireless communication standards consisting of GSM, WCDMA, WLANa, WLANb, WLANg and WiMAX is focussed. Decimation is done in two or three stages to reduce the hardware complexity and power dissipation. Each stage is implemented with optimized filters so that the overall cascaded filter response meets the specification for a particular standard. The decimation filter design tool is developed using the graphical user interface development environment (GUIDE) in Matlab^reg. The implementation complexity in terms of filter length that meets the specification for any of these standards is computed using this tool and is tabulated.
