ABSTRACT:
A non-coherent BPSK demodulator which responds to a predetermined pseudo-noise received data code to generate a series of pulses whose pulse widths indicate a timing difference between the received data code and a simulated data code is disclosed. Inverted portions of the predetermined data code are detected and corrected. Ambiguous pulses and pulses having inconsistent widths are removed from the generated series of pulses.
