Influence of the parameters of the DVB-S/S2 standards on the capacity of a satellite transponder

In this paper, the influence of the basic parameters of the satellite transponder on its capacity is analyzed. Using DVB Calculator, the influence of modulation formats (QPSK, 8PSK, 16APSK and 32APSK), FEC parameters, Roll-Off factors and Frame Length on Bit Rate and Symbol Rate of satellite transponder are analyzed. The table shows the Bit Rate for various DVB-S and DVB-S2 standard combinations.
