The Reactive power compensator and monitor of Power factor system is designed based on ARM7, with function of long distant transmission. It monitors and measures alternation current parameters, such as the active and reactive electric energy, active and reactive power, voltage, current, power factor and other parameters. To realize reactive compensation, it can automatically switch shunt compensation...
On-line real time automatic communication signal?? Frequency Modulated (FM) signal recognition has been a hot topic recently, which focuses on finding the characteristic feature in the noisy signal observations comprehensively identifying the the same or different version of transmitting devices with approximate performance parameters in modern electronic warfare. Direct use of Higher Order Statistics...
Feature extraction of FM signal is the first and most important step in modern automatic communication signal recognition. Based on the real-world collected silent FM observation, a systematic method for feature extraction of FM signal is presented after an intensive experiment modeling analysis, which includes Hilbert Transform and the key robust single-tone parameter estimation technique---FFT-based...
Feature extraction of FM signal is the first and most important step in modern automatic communication signal recognition. Based on the real-world collected FM signal, a systematic method for feature extraction of FM signal is presented after an intensive experiment modeling analysis, which includes Hilbert Transform and the key single-tone parameter estimation technique-integrated FFT-based interpolation...
Accurate and high-performance frequency estimation of a noisy sampled sinusoid sequence with short time length and adjacent overlapping has been attracting top focus in the field of signal processing. Based on the CZT of a single-tone sequence, this paper presents a novel improved Rife CZT-interpolated frequency estimator, which develops an improved Rife algorithm on the symmetry of CZT Linear Spectrum...
