Carrier phase tracking performance of a digital PLL under low SNR conditions for spread spectrum TT&C links
This paper presents the analysis of the carrier phase tracking performance of a third-order digital phase-locked loop (DPLL) in low signal-to-noise ratio (SNR) spread spectrum telemetry, tracking, and command (TT&C) systems. A signal model is established in the post-despreading period, and the steady-state phase error...

Adaptive filtering and signal reconstruction methods for high-precision electrical parameter measurement systems
Aiming at the problem that the complex electromagnetic environment leads to the decline of electrical parameter detection accuracy and the lag of transient response under the background of new power system, a highly robust signal processing technology scheme is studied. Firstly, a mathematical model of mixed interferen...

Saturation-enhanced dynamic regressor extension for robust carrier frequency estimation of disturbed amplitude-modulated signals
This paper considers the problem of carrier frequency estimation from measurements of an amplitude-modulated signal in the presence of unknown bounded disturbances and a time-varying envelope. Existing identification methods based on regression transformations usually require a small-disturbance condition, which limits...

Comparative Analysis of First-Order, Second-Order, and Fourth-Order Low-Pass Filters in Amplitude Modulation Synchronous Demodulation Systems
. Amplitude Modulation (AM) is both a ubiquitous modern communication technology and is used extensively in the low-power Internet of Things (IoT). In real-life settings, noise in a channel, system flaws, and electromagnetic interference are major factor that plagues the quality of communications, and this aspect requi...

Evaluation of the Modified Covariance Method Performance with Cleaning Characteristic Harmonic Digital Filter in Protection Relay
Under harsh transient situations, contemporary protection relays necessitate the accurate and swift estimation of phasors. The prior CCHDF filter was limited by DFT techniques and utilized the Biunivocal Frequency Relationship of Phasors (BFRP). The Modified Covariance Method (MCM) is a sophisticated autoregressive spe...

Discrete-Sampling-Induced Time Resolution Limits in Two-Way Time Synchronization
High-precision time synchronization refers to the process of achieving and maintaining coordination among independent clocks via the exchange of local and remote time information. Existing analyses of digital receiver delay estimation often rely on an ideal continuous autocorrelation function (ACF), whereas practical r...
