Title :
Performance analysis of a high resolution time delay estimation algorithm
Abstract :
The convergence properties of an iterative algorithm for high-resolution time delay estimation are studied for a specific example. It is shown that the functional relationship between successive iterates is a contraction mapping for high signal-to-noise ratio. The contraction mapping condition is shown by deriving the derivative of the functional relationship and then calculating the mean and variance of the derivative. The analytical computation is validated by computer simulation
