System and hardware design considerations for companded single sideband satellite equipment
Abstract
The underlying system design is described for the CM72 companded single sideband satellite system, which transmits over 7200 channels in a 36-MHz transponder. It is noted that the CM72 is intrinsically multiple access, and that its applications include high and medium density routes for both C and Ku band; at Ku band the CM72 is especially attractive for both voice and data transmission and it can be configured in a demand-assignment arrangement. A link noise budget is derived that includes all sources of intermodulation, interference, and noise. The equipment design concepts are described, and attention is given to specific approaches to the problems of frequency plan, frequency control, amplitude control, phase jitter, and reliability.
