A new method of variance estimation based on wavelet packet de-noising;

On the basis of wavelet packet tree structured signal sets,this paper generalizeds the TSOJD algorithm to complex field for QPSK signals Besides,via the computer simulation,we explore the performance of TSOJD receiver and the effect of phase offset on it The simulation results indicate that the algorithm could achieve good tradeoff between computational complexity and performanc

Using the quantum Gaussian wave packet analysis method,we calculate the autocorrelation function of the rectangular billiard,the peak positions of the autocorrelation function match well with the periods of the classical periodic orbits,which show that the period of the classical orbits can be produced by the time-dependent quantum wave packet .

This paper deduce the average force exerted by a circularly polarized electromagnetic wave on an atomic wave packet .

With the multielectronic states model for investigation of molecular behavior in superstrong laser fields,we simulate numerically the evolution procedure of a molecular wavepacket in the superstrong laser field.

An exact three-dimensional time-dependent quantum wave packet was used to calculate the He+H2+ reaction using the potential energy function of HeH2+ [1].

Full three-dimension time-dependent quantum wave packet calculations have been carried out for H+HBr reaction on the latest analytical ab initio potential energy surface.

The goal of this paper is to generalize the notions and properties of wavelet packet to produce biorthogonal multiwavelet packet,and to develop the theoretical framework of biorthogonal multiwavelet packet,which makes more kinds of signals for analysis with multiw.
