Abstract:To cut down the implementation cost in Wireless Sensor Networks receiver,a digital front-end filter design method with optimized transposed architecture and optimized CSD coefficient representation is proposed.By implementing above filter on Xilinx Virtex II 2000 series FPGA,good performance as well as resource saving effect has been observed.The method of optimized CSD coefficient representation can be applied not only to front-end filter of Wireless Sensor Networks,but also to other constant coefficient f...
