Abstract

The design and simulation of the digital decimation part for wideband code division multiple access (WCDMA) based software defined radio (SDR) technology is presented in this paper. A system level design tool, SIMULINK and FDA Tool an environment in MATLAB is adopted together in the design sequence to give digital decimation higher efficiency. The proposed decimation filter includes three cascaded FIR filters. The residual sub modules of the decimation filter, such as FIR filters, participated in its design using MATLAB with the trade-offs between the considerations to get through the requirements of WCDMA, and the complexity of the algorithm and simulation. Finally, the decimation filter is simulated on MATLAB SIMULINK block set and its performance is also addressed and tested using FDA Tool and that supports current and future generation of wireless and mobile systems.
