Abstract

978,194. Carrier frequency multiplex systems. COMPAGNIE FRANCAISE THOMSON - HOUSTON. May 12, 1961 [May 13, 1960], No. 17407/61. Headings H4L and H4R. In a single-sideband suppressed carrier multi-channel radio-communication system one or more additional channels are transmitted as double-sideband signals and utilized to synchronize the locally generated carrier at the receiver. Specification 815,601 is referred to.
