A 5400 Voice-Channels Single Side Band Amplitude Modulated Radio Relay System Operating in the 4 GHz Band
Pierre Ramat, D. Thebault, C. Veyres · 1980
The present study intends to show the feasibility of a SSB-AM microwave link. A laboratory model of a transmitter-receiver working in the 3,8 - 4,2 GHz band was constructed and allows 5400 voice-channels to be transmitted for a 29 MHz-bandwidth channel. Subsets linearity and propagation selective fading problems were more specifically investigated.
