New improvement of Gerschgorin Radii Base on Jacobi Method for Source Number Estimation
Abstract— In this paper, a new improvement of the classical gerschgorin disk method based on Jacobi
method is proposed. Results of the analysis and the computer simulations are showed that the improved
method consumes less multiplications and additions. It also has the same performance of the classical
gerschgorin disk method. In a word, this new approach not only can reduce the consumption of resource and
time, but also has a good performance of the sources number estimation. Compared with the classical
gerschgorin disk method, this new method base on Jacobi method iterative structure, is more easy to
implement in FPGA and DSP.
