DVB-RCS2 is the 2nd generation standard defining a return channel via satellite. It achieves better performance by using the more advanced 16-states double-binary turbo codes compared to the 8-states counterparts of its predecessor DVB-RCS. Thus far it is the only standard that uses 16-states double-binary turbo codes. Due to the support of new mappings (8-PSK, 16-QAM) it offers higher data rates and an improved spectral efficiency.
