In this paper, a joint parameters estimation problem in the multipath environment was studied. In the view of the drawback what the classic ESPRIT algorithm does not fully utilize the information provided by channel response matrix, so a joint estimation method based on the eigenvalues and eigenvectors was put forward. This algorithm estimates the delay and angle for only one eigenvalues decomposition...
The problem, of finding extreme eigenvalues and eigenvectors of a real symmetric positive definite matrix can be viewed as a smooth optimization problem on a smooth manifold. We present a cost function approach for computing higher dimensional sub-spaces corresponding to smallest and largest eigenvalues simultaneously. This approach is then generalized to develop dynamical system for computing the...
High-resolution parameter estimation techniques have recently been applied to jointly estimate multiple signal parameters. In this paper, we consider the joint frequency and 2-D DOA estimation problem. We define a novel space-time matrix which includes the information of incident frequencies and 2-D DOAs. The joint frequency and 2-D DOA estimation method used the defined space-time matrix is named...
This paper first formally defines a general class of three dimensional rectifier systems which capture the essential aspects of animal locomotion, then formulates an optimal gait problem, and finally solves an approximation of the problem to obtain a globally optimal solution. The approximation assumes small-amplitude harmonic oscillations of mechanical joints about a nominal posture. The problem...
