Abstract: This Paper Investigates The Design Of Programmable Decimation Filters To Be Used In The Channelizer Of Multi-Standard Software Defined Radios Receivers. The Technique Of New Algorithms For Reducing The Passband Ripple Of Linear Phase Fir Digital Filters Which Minimizes The Passband Deviation In The Decimation Block Is Introduced And Is Used To Implement A Multistage, Multi-Standard Decimating Filter. The Design Will Enhanced Different Communications Standards And Is Thus Ideal For Use In Systems Which Support Dynamic Reconfiguration. Results Obtained Shows An Important Reduction In The Passband Ripple In The Decimation Part From 0.03 Db To 0.012 Db And High Reconfigurability In The Filtration Requirements.
Keywords: FIR, SDR, Digital down-converter, GSM, Equiripple FIR, Passband ripple, Adjacent band Rejection, blocker Requirements.
