This invention relates to a novel receiver architecture, the Charge-Coupled-Device Integrated Receiver (IR), which simplifies electronic circuitry requirements and reduce baseband processing rates through efficient signal processing. The focus of this receiver\s design is its use of Charge-Coupled-Device (CCD) technology. By using CCD\s, in conjunction with other key technologies, to implement the signal processing techniques disclosed herein, it is possible to provide a receiver that is suitable for a wide range of applications (e.g., communications, sonar, radar, etc.). Information is presented which outlines the fundamental receiver architecture that is appropriate for a wide range of commercial services (e.g., AMPS, NAMPS, Digital Cellular, GSM, PCS, ISM, CT1, CT2, etc.) Furthermore, tile versatility of this architecture makes it suited for uses ranging from simple AM/FM receivers to complex high-order modulation TDMA/CDMA receivers.
