An algorithm of frequency estimation for multi-channel coprime sampling
In some applications of frequency estimation, it is challenging to sample at as high as Nyquist rate due to hardware limitations. Based on conventional ESPRIT, a new method for frequency estimation with double-channel sub-Nyquist sampling is proposed. When the two undersampled multiples are relatively prime integers, partial samples are selected to estimate the frequency components contained in...
متن کاملRate distortion performance analysis of nested sampling and coprime sampling
In this paper, rate distortion performance of nested sampling and coprime sampling is studied. It is shown that with the increasing of distortion, the data rate decreases. With these two sparse sampling algorithms, the data rate is proved to be much less than that without sparse sampling. With the increasing of sampling spacings, the data rate decreases at certain distortion, which is because w...
متن کاملTransition rate prefactors for systems of many degrees of freedom.
When a minimum on the potential energy surface is surrounded by multiple saddle points with similar energy barriers, the transition pathways with greater prefactors are more important than those that have similar energy barriers but smaller prefactors. In this paper, we present a theoretical formulation for the prefactors, computing the probabilities for transition paths from a minimum to its s...

متن کاملStochastic Optimization for Vibrational Systems of Multi-degrees of Freedom
A prohahilistic approach to design variables optimization of mechanical systems of multi ~ degrees of freedom is presented. The proposed method is based on the mathematical modelling of the systems, Optimization is understood as a calculation of the mean values and standard deviations of the random parameters chosen from the set of all design variables, which in the feasible domain minimize the...
