Satellite Earth Stations and Systems (SES); Satellite Component of UMTS/IMT-2000; Part 3: Spreading and modulation; Sub-part 3: G-family enhancements (S-UMTS-G enhanced 25.213) (V3.1.1)
The present document describes spreading and modulation for the Physical Layer for family G enhanced of the satellite component of UMTS (S-UMTS-G enhanced). It is based on the FDD mode of UTRA defined by TS 101 851-1-3 [1]@ TS 101 851-2-3 [2]@ TS 101 851-4-3 [3] and adapted for operation over satellite transponders. Furthermore@ it specifies enhancing features optimizing the basic G family radio interface performances over satellite and new functions.
