Abstract
A method for identifying occurrence of shadowing phenomenon is to be implemented using a wireless communications system that includes signal transmitting and receiving devices. The signal-receiving device periodically executes a synchronization process to evaluate quality of wireless communications conducted through a signal transmission path between the signal transmitting and receiving devices. A set of signal-state estimated values that includes phase and power parameters is generated during each synchronization process. The method includes: collecting the phase parameters for a number of the synchronization processes; generating a set of Poincaré coordinate data from the collected phase parameters; analyzing distribution of the set of Poincaré coordinate data on a Poincaré map; and determining that the signal transmission path is experiencing a shadowing phenomenon in case of a non-elliptical distribution.
