JELE_V4_N1_RP3 Sandhiya Vijayakumar S. Karthick M. Valarmathy Journal on Electronics Engineering 2249 – 0760 4 1 24 34 Software Defined Radio (SDR), Channelizer, FIR filter, Common Subexpression Elimination Sandhiya et.al developed CSM and PSM approaches for implementing reconfigurable higher order filters with low complexity. Greedy CSE (Common Subexpression Elimination) algorithm is applied for achieving reduction in complexity. Binary based fir filter gives 33% better reduction than CSD based CSE method. Finally, mentorgraphics tool and Xilinx(synthesis) are used to simulate and compare the results of CSD and Binary based CSE, greedy, VCSE and HCSE techniques for finding the best one adder reduction method in low complexity FIR filter.
