High Throughput Terminal/CDMA Modem for Satellite Communications

摘要

Communications on the battlefield can benefit from the use of satellites to support connectivity over widely dispersed deployments and rugged terrain. It appears that satellite communications for military purposes will be enhanced using Code Division Multiple Access (CDMA). The spread spectrum technology used for CDMA has provided terrestrial military communication systems with many positive features including anti-jamming, Low Probability of Detection (LPD), and Low Probability of Interception (LPI). CDMA can also be used to gain increased capacity, improved coverage, reduced transmission power, and extended range. This proposal describes a CAD approach to rapid analysis and design of communications systems. Based upon PSI's real time control and simulation environment, it has been used for development of dynamic real time data and communication systems. This environment consists of the General Simulation System (GSS) for discrete event simulation and the Visual Software Environment (VSE) for building real time control systems. On top of these tools, PSI has developed a new Run Time Graphics (RTG) system that allows the analyst to graphically monitor and interact with the live system as well as a simulation. This environment is directly applicable to the rapid development of CDMA technology for use in satellite communications.
