This report describes current capabilities of the Interactive Communications Simulator ICS and the models employed in it. The ICS is a computed-aided modeling, simulation, design and analysis tool for a wide variety of point-to-point digital communication systems. The simulator has been used to evaluate existing modem performance, and to explore new modulationcoding and signal processing concepts pertinent to military, commercial, and space applications. The ICS is a flexible, graphics oriented, high speed, high resolution, and user friendly hardwaresoftware system consisting of a PDP 11 series or VAX minicomputer acting as host to a peripheral array processor, the Floating Point Systems AP-120B or FPS100. It employs a fixed modeling topology to represent communication links their signal processing functions sourcesink, source encodingdecoding, channel encodingdecoding, modulationdemodulation, transmitterreceiver, propagation channels and electronics interferences. It has an extensive graphics package, channel and filter design packages, and many powerful analysis subroutines, to facilitate user interactions, link design, analyses, and output displays. All simulation modules representing signal processing functions and some analysis subroutines are written in AP Assembly Language, all other software are written in DEC FORTRAN. Keywords includes Communication Link Modeling and Simulation, Communication Signal Processing Techniques, Computer-aided Design and Analysis Tool.
