Abstract:

A discussion of the design, and construction and use of a Pseudo-Noise Sequence GeneratorCorrelator and a Flexible Spread Spectrum System in which it is employed is presented. This equipment is an educational tool for instruction, research and demonstration of spread spectrum techniques. Pseudo-Noise sequences of lengths 7 through 4095 are generated and used to spread a signal over a maximum bandwidth of approximately 15 MHz. Signals spread over a bandwidth of 5 MHz or less may be successfully recovered by means of a Delay-Lock Tracking Loop. Linear and hardlimited channel configurations are available. Message bandwidths up to approximately 28 kHz are accommodated. While designed as an educational tool, the Flexible Spread Spectrum System has a stand-alone capability as a cable communications system.
