An Approach to the Development of Software for Computer-Aided Design of Satellite Communications Receivers for Operation in Scintillating Channels
Abstract
An extensive inventory of techniques to provide robust communications to nuclear-disturbed signal propagation channels has been developed and tested over the past decade. The work described herein is intended to facilitate the process of placing these mitigation techniques in the hands of the designer through the development of a computer-aided design (CAD) software package . To maximize its utility, the CAD software is being developed to run on desktop personal computers (PCs). When developed, this software will allow signal statistical parameters obtained from Defense Nuclear Agency signal specification and from Nuclear Criteria Group signal criteria to be readily incorporated in the communications link design process. The PC-based CAD software will enable the designer to input communications system characteristics that may be constrained by other considerations, together with DNA specifications of disturbed signal parameters that the system must be designed to withstand. The CAD software will then provide information on modulation, demodulation, tracking, coding, and diversity requirements to obtain specific levels of performance over specified ranges of nuclear disturbances. when fully developed, the CAD software should significantly simplify the design of robust digital communications systems that must operate in fading radio channels.
