Estimating sub-pixel shifts directly from the phase difference
In this paper, we establish the exact relationship between the continuous and the discrete phase-difference of two shifted images, and show that their discrete phase difference is...

Computing Phase Noise Eigenfunctions Directly from Steady-State Jacobian Matrices
The main effort in oscillator phase noise calculation lies in computing a vector function called the Perturbation Projection Vector (PPV). Current techniques for PPV calculation u...
