Abstract

The new bandwidth-efficient DVB-S2 (EN302307) standard, the successor of DVB-S and DVB-DSNG is designed to address the challenges of cost-effectively transmitting high-quality video and advanced services via satellite. This paper focuses on the design and implementation of SRRC filter as part of the Baseband shaping and Quadrature modulation module of DVB-S2 standard for the three rolloff factors 0.20, 0.25, and 0.35. It is a pulse shaping filter which aims at minimising ISI.Direct form symmetric structure of FIR filter is used to design SRRC filter of order 96using MATLAB and FPGA implemented using ALTERA Quartus II.This paper will deliver the results of SRRC filter for different roll-offs along with the performance gain comparisons of DVB-S and DVB-S2 roll-offs.
