TLDR
The performance of phase-locked or delay-locked loops is dependent both upon the signal-to-noise ratio (SNR) of the received signal and the detailed structure of the local reference signal.Abstract:
The performance of phase-locked or delay-locked loops is dependent both upon the signal-to-noise ratio (SNR) of the received signal and the detailed structure of both the received signal and the local-reference signal. Optimum signals for first-order delay-locked loops are determined as functions of the loop SNR using simple optimization criteria.read more

A bibliography of the theory and application of the phase-lock principle
W. C. Lindsey,R. C. Tausworthe +1 more
TL;DR: A literature search was conducted in an effort to collect and compile as many references on the phase-locked loop as possible, and a comprehensive listing of approximately 800 references covering the past two decades of work reported throughout the world are presented.

Andreas Polydoros,S. Glisic +1 more
TL;DR: The main concepts underlying the derivation of appropriate receivers for code synchronization in spread spectrum systems are reviewed, emphasizing a likelihood theory viewpoint.
A Method to Dramatically Improve Subcarrier Tracking
W. J. Hurd,S. Aguirre +1 more
TL;DR: In this article, the amplitude of the phase quadrature reference signal is set to zero except near the zero crossings of the input signal, and the window can be made so narrow as to achieve a phase error variance of 1.5 sigma(sub 0)(4).

A method to dramatically improve subcarrier tracking
W. J. Hurd,S. Aguirre +1 more
TL;DR: A method is presented for achieving a considerable improvement in phase tracking of square-wave subcarriers or other square waves and establishes minimum W versus SNR (signal-to-noise ratio).

Tracking performance of improved delay-lock loop
TL;DR: The improved DLL (IDLL-1) with extended range of discriminator characteristic is proposed, which consists of IDLL-2 and simple circuits, which is proposed to compensate the fault of DLL.

Phase-locked loop dynamics in the presence of noise by Fokker-Planck techniques
TL;DR: In this paper, the phase-error behavior of a phase-locked loop tracking a constant frequency signal in the presence of additive, stationary, Gaussian noise is studied. But the model is based on a continuous random walk with a sinusoidal restoring force.

Delay-Lock Tracking of Binary Signals
TL;DR: The theory of operation and an evaluation of performance of a delay-lock tracking system for binary signals for target search and acquisition and of the effect of amplitude-limiting the received data on the system noise performance are presented.

On the Selection of Signals for Phase-Locked Loops
TL;DR: This paper is concerned with the problem of selecting both the input and local signals so as to minimize the tracking error due to additive noise.
Correction to "Phase-Locked Loop Pull-In Range"' Minimization of Communication-Signal Acquisition Time in Tracking Loops
Paul D. Shaft,Richard C. Dorf +1 more
TL;DR: In this paper, the nonlinearity that minimizes the acquisition time is determined, and a bound on the lock-on per-formance for arbitrary nonlinear functions is also obtained.
