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 samples 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 for governmental 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.

Potential Commercial Application:

Potential Commercial Applications: 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.
