Design of Variable Interpolated Filter CIC in DVB-S and Its FPGA Realization
Lirong Shi · Modern Electronics Technique · 2008
In this paper,a new variable interpolated filter in DVB-S(Digital Vidoe Broadcast by Satellite) is introduced based on the common filter of cascaded integrator comb.Firstly a CIC filter module with interpolation factor 2 is designed,then we could reuse the basic module according to the interpolation factor.Based on the theory of CIC filter,the filter with FPGA is simulated and synthesized,the results is given,and realizes it in the system of DVB-S.
