Realization ofLow-Cost Spectrum ShapingFiter for Digital Radio-RelaySystems with DirectModulation
M. Zecevic, Miroslav V. Peric · 2005
Inthis paperwe described therealization oflowcost spectrumshaping filter fordigital radio-relay systems with direct modulation, whichismadeas a cascade connection of digital FIRandanalogue Butterworth filter. FIRfilter operates attwicethesymbolrate, anditscoefficients are chosenfor minimisingFPGA or CPLD chipresourcesneededfor realisation.
