The Application of Charge-Coupled Devices to Spread-Spectrum Systems

The application of charge-coupled device (CCD) technology to spread-spectrum systems is presented. In particular, CCD pseudonoise matched filters and recursive integrators are described functionally and as semiconductor devices. Then, applications to various modulation formats are considered in terms of integrated circuit architecture. Acquisition and synchronization for directsequence and hybrid frequency-hopping spread-spectrum systems are also covered. Finally, random time-division multiple-access acquisition and data demodulation are considered.
