Feature extraction plays an important role in machinery fault diagnosis and prognosis. The features extracted from time, frequency and time-frequency domains are widely investigated to describe the properties of overall signal from different perspectives, seldom considering the sequential characteristic of time-series signal in which the fault information may be embedded. This paper investigates a...
This work presents a joint synchronization technique for DVB-H system with adaptive FFT mode detection, guard interval length detection, coarse symbol synchronization (CSS) and fractional carrier frequency offset (FCFO) estimation. Different from conventional algorithm, we develop a threshold-free scheme which is more reliable in frequency selective fading channel. Simulation results show almost 2...
