Simultaneous Transmission of Facsimile and Message Traffic Over a Microwave Baseband

This paper addresses itself to the problem of adding a high-speed graphic, supergroup bandwidth data channel to an existing message loaded baseband. The complete results of a numerical approach obtained by use of a digital computer are presented, as well as practical design curves developed to assist system planners in calculating peak-to-rms factors and rms value of composite, data-plus-message, baseband loading. The analysis deals with one facsimile supergroup added to an existing microwave telecommunication system.
