A field test for companded single sideband modulation Implications for capacity enhancement and transmission planning
Abstract
A series of field tests of companded single sideband modulation (CSSB) technique for use in the Intelsat system is described. A 12-channel circuit group was tested between switches in Pittsburgh, and the Deutsche Bundespost (DBP) in Frankfurt via the Etam and Raisting satellite earth stations. A transponder bulk that included existing FDM-FM carriers was chosen to match the typical, Intelsat operating conditions, thus permitting the compatibility of FDM/FM and CSSB to be examined simultaneously. Results of objective performance tests are discussed, and a description of several subjective testing techniques is also given.
