Satellite communication systems for domestic/business services
Abstract
Implementation aspects and performance characteristics of FDMA/TDMA systems operating at Ka band for business services applications are considered. A modular regenerative and processing satellite repeater, with each module capable of handling up to 16 up-link carriers in the 2 Mb/s range, is discussed, and a compensation method for keeping stable the up-link carriers in the satellite demodulators is proposed. Implementation of a multifrequency TDMA system is also considered, and the adoption of a clock synchronous network allows a frame for which no preamble and guard time need be used. A fast phase/frequency estimation approach is discussed.
