Patent
Adaptive electronically steerable phased array
TL;DR: In this article, an adaptive antenna system which enhances the desired signal in the output of the system while reducing the interference from signals arriving from directions other than that of a desired signal is presented.
Patent
Digital coherent phase demodulator
TL;DR: In this paper, a digital system for demodulating coherent phase shift keyed signals is proposed, where the maximum likelihood estimates of the unmodulated phase and rate of change of the phase of the received signal relative to a local oscillator signal are used to improve the demodulation process.
Patent
Combined coherent frequency and phase shift keying modulation system
TL;DR: In this article, a system of modulation and demodulation for the transmission of binary data in the presence of multipath was proposed, where the binary data modulates the phase of the carrier and the same binary data, after a delay of "δ" bits, also modifies the frequency of the operator.
Patent
In-phase quadrature demodulator for CPSK signals
TL;DR: In this paper, a system for demodulating a coherent, phase-shift-keyed signal that is modulated by a set of orthogonal or biorthogonal code words is presented.
Patent
Signal frequency synthesizer
TL;DR: In this paper, a plurality of binary related anti-coincident pulse trains which are precisely related in frequency and phase to a reference frequency are generated in a binary rate multiplier.
