Abstract
AN INNOVATIVE TECHNIQUE WILL BE INVESTIGATED TO ACQUIRE AND DIGITIZE A PACKET OF HIGH-DATA-RATE BURST INFORMATION. IN THIS CONCEPT, A CHARGE-COUPLED DEVICE (CCD) SAMPLES THE RECEIVED SIGNAL AND DETECTS THE UNIQUE SYNCHRONIZATION WORD.UPON UNIQUE-WORD DETECTION, THE TIMING OF THE DATA BURST IS DETERMINED, AND THE CCD DEVICE TEMPORARILY STORES THE BURST-SIGNAL SAMPLES. THESE SIGNAL SAMLES ARE THEN OUTPUT AT A SLOWER RATE COMPATIBLE WITH A MICROPROCESSOR, SIGNAL PROCESSOR, OR OTHER LOW-DATA-RATE DEMODULATOR. THIS DEVICE PROMISES TO GREATLY SIMPLIFY THE CIRCUITRY OF TIME-DIVISION MULTIPLE ACCESS (TDMA) AND OTHER BURST-DATA DEMODULATORS FORGOVERNMENTAL AND COMMERCIAL COMMUNICATIONS. IT CAN BE USED IN A TDMA RECEIVER TO ACHIEVE A LOW COMPLEXITY WITH A LOW AVERAGE DATA RATE AND VERY HIGH INSTANTANEOUS DATA RATE, E.G., 1500 MEGABITS PER SECOND. THIS EFFORT COULD BE THE BASIS FOR APPLICATIONS IN TDMA LOW-COST GROUND TERMINALS, HIGH-CAPACITY TDMA RECEIVERS, RANDOM-ACCESS PACKET RECEIVERS, AND OTHER BURST SIGNAL SYSTEMS. THE APPROACH ALLOWS VERY SMALL, LOW-POWER, BURST-MODULATION,MULTIPLE-ACCESS TERMINALS, E.G. HAND-HELD OR SINGLE BOARD DEMODULATORS.
