Rice statistical propagation channel sounding: coherence bandwidth measurement by microwave interferometric sensor

Numerical and wireless communications systems are led by the coherent frequency bandwidth (BC) of the propagation channel where the wireless link is considered. An original method is presented to achieve the BC of a channel having a Riceʹs statistic law (one or more paths are without reflection between transmitter and receiver) which is based on the mitigation, by using a microwave interferometric sensor and a narrowband multitone transmitter, of the phase difference error due to multipaths.
