Abstract : This interim report covers the work performed under the application of Surface Charge Transistor (SCT) Correlator to Wideband Communications Contract. The study included both a theoretical evaluation of CCD's, as a signal processing/memory element for the next generation spread spectrum communications and an experimental evaluation of the SCT correlator device in a high gain signal processing system, an adaptive receiver. The objective of this study was to investigate the application of charge coupled devices (CCD's) in optimal performance of adaptive signal detection and to project the potential inherent in CCD devices to cost effectively detect spread spectrum multifunction signals transmitted over line-of-sight multipath fading channels. Both SCT correlator chips and CCD memories were to be combined to achieve optimal data detection. Also, an experimental communications model was to be synthesized, breadboarded, and evaluated as the most promising candidate for application of the SCT correlator chip to Wideband Communications.
