Chaos characteristic analysis of the phase-locked loop (PLL) synthesizer has been made in this paper based on the phase model of it, and we conclude the state equation of this model and the condition when the system becomes chaos. Because the paramet

Practical signals such as communication and radar signals turn out to be non-stationary and nonlinear time series, and estimating instantaneous parameters of such signals in time domain will benefit detecting and identifying specific emitters, such a
The empirical mode decomposition (EMD) method for analysing nonlinear and non-stationary data has attracted great research interests. Because, the TH-PPM UWB signal which has the property of transient and low probability of intercept (LPI) is non-sta

The problem of spectral estimation in reverberation noise is considered in this paper. Since the reverberation is inherently deterministic, a new complexity measure called the phase space volume (PSV) is introduced for estimation instead of using the

There many researches about modulation mode classification of the MPSK signals, but these studies pay few attentions to some especial MPSK signals such as OQPSK or π/4QPSK. However, the signals are very important in the digital communications. The m
