Phase-locked loops (PLL's) may be used to implement signal combiners which coherently
sum multiple signals from an array of sensors. In each combiner channel, the sensor signal …

We discuss several designs for self-steering array combiners together with a simple
frequency-offset tagging method which permits locking of a combiner to one of serveral …

The performance of phase-locked loops and related signal tracking devices is dependent
upon the cross-correlation function between the input signal and a locally generated signal …

Proposed is a new carrier phase synchronisation scheme used to provide a stable phase
reference to a very distant station. Channel induced phase fluctuations are characterised …

A digital phase-locked loop (DPLL) bit synchronizer that tracks the zero crossings of a
bandlimited binary signal is discussed. The synchronizer reduces pattern jitter or self noise …

The phase and amplitude errors of a phase-insensitive coherent (homodyne) detector are
analyzed. The detector consists of two balanced mixers which are fed in quadrature phase …

A multireceiver configuration for the purpose of carrier arraying and/or signal arraying is
presented. The configuration is arrived at by formulating the carrier and/or signal arraying …

This thesis analyzes the joint effects of RF carrier phase error and synchronization error in a
Two Way Coherent Communication System. The transmitted signal consists of a binary data …

A new approach to time-domain multiplexing of fiber-optic sensors is presented: a
synchronization pulse is sent back only by the questioned sensor. This selective …

A system is proposed that allows the phase and amplitude of a signal to be accurately set
and regulated over process and power supply variations. The intended application is in a …
