Low Cost Waveform Digitizer for Physics Using Advnaced Computer Graphics Technology

Not Available Code Division Multiple Access (CDMA) is currently being applied to satellite technology to support communications requiring large areas of remote coverage. CDMA technology can be used to provide cost-effective satellite network communications by increasing throughput capacity and providing better signal quality. Spreading the signal using CDMA also provides inherent military advantages such as secure communications and denying enemy attacks such as jamming, ranging, and direction finding. It is very desirable to develop CDMA based systems that can be implemented using Commercial Off-The-Shelf (COTS) available hardware components. Within this proposal, PSI proposes the development of a CDMA Satellite Modem Design Facility that can be used to design and analyze CDMA technology for use over satellite systems. This simulation facility can be used to optimize the implementation of CDMA satellite modems to support military communications on the bafflefield as well as other comrnunication requirements that cannot be supported by terrestrial communications. The facility will also be able to support the stimulation of CDMA modem prototypes as they are developed. This technology is also being sought by the commercial sector. The Design Facility can be used by commercial providers of satellite services to optimize the use of their systems. Maximizing the performance of satellite system usage will reduce the number of satellites that need to be launched. This will greatly reduce setup and operation costs as well as reduce the depletion of available satellite orbits.
