Inventor(s)Dixon; Robert C. (Palmer Lake, CO)
AbstractA phase coded surface-acoustic-wave-correlator device used with a spread spectrum receiver. The spread spectrum receiver receives a spread spectrum signal which has a carrier signal with a phase modulated by a data-bit sequence and by a chip sequence. The chip sequence is repetitively and coherently generated with each bit of the data-bit sequence and is modulated with one period of the chip sequence. The surface-acoustic-wave-correlator device is phase matched to the chip sequence. The surface-acoustic-wave-correlator device outputs a post-SAWC-signal pulse having the carrier signal phase modulated by the data-bit sequence. A phase detector detects the phase of the carrier signal and generates the data-bit sequence.
