ABSTRACT:
A method for estimating the phase in a digital communication system, comprising the steps of:receiving and storing a block of observations Yk;executing at least one phase locked loop (PLL) on a predetermined sequence of observations extracted from said block.Each PLL provides an intermediate value, combining both intermediate values makes it possible to provide a sharpened phase estimate. The method allows realization of an improved phase estimator based on the simplicity of phase locked loops.
