NUCLEAR EFFECTS SIMULATION: COMPUTER-AIDED DESIGN OF SATELLITE COMMUNICATIONS RECEIVERS FOR OPERATION IN SCINTILLATING CHANNELS

THE OBJECTIVE OF THE PROPOSED EFFORT IS TO DEVELOP A SOFTWARE PACKAGE TO FACILITATE THE DESIGN OF DIGITAL COMMUNICATIONS EQUIPMENT TO PROVIDE SPECIFIED LEVELS OF PERFORMANCE IN NUCLEAR-DISTURBED PROPAGATION ENVIRONMENTS HAVING SPECIFIED RANGES OF SIGNAL SCINTILLATION PARAMETERS (...). THIS SOFTWARE PACKAGE WILL ALLOW SIGNAL STATISTICAL PARAMETERS OBTAINED FROM DNA OR NCGS SPECIFICATIONS TO BE READILY INCORPORATED INTO THE COMMUNICATIONS LINK DESIGN PROCESS. THE RESULTING PERSONAL COMPUTER (PC) BASED COMPUTER-AIDED DESIGN (CAD) PACKAGE WILL ASSIST THE LINK DESIGNER IN MAKING APPROPRIATE CHOICES OF MODULATION, CODING, TRACKING, AND DIVERSITY TECHNIQUES TO ACHIEVE THE SPECIFIED LEVELS OF PERFORMANCE OVER THE SPECIFIED RANGES OF NUCLEAR DISTURBANCES.
