Patent Number Title Of Patent Date Issued
4305159 Compressive receiver December 8, 1981
The envelope detector of a compressive receiver is replaced with either a Fourier Transform device or a demodulator such that the output of the dispersive delay line utilized in the receiver is processed to yield the spectrum of the incoming signals and/or the modulation impressed on the
4247939 Spread spectrum detector January 27, 1981
A spread spectrum detector utilizes compressive receiver techniques and squaring of the incoming signal to detect the presence of a spread spectrum signal and to obtain its center frequency, with the squaring cancelling the pseudo-random code. Once having determined the center freque
