Antenna-diversity receiver and method of operating an antenna-diversity receiver and a transmitter in a frequency-hopping communication system

摘要

An antenna-diversity receiver receives data units from a transmitter in a frequency-hopping communication system. The frequency-hopping system has a channel set comprising of multiple channels, each having its own frequency range. The channel set comprises a set of multiple advertising channels and a set of multiple data channels. The receiver comprises an antenna set of multiple antennas.;The transmitter has an advertising mode in which the transmitter transmits an advertising signal and switches from one advertising channel to another advertising channel in accordance with a sequence of advertising intervals, each advertising interval comprising an advertising packet.;The receiver has an antenna sampling mode in which the receiver receives, successively for each combination of antenna and advertising channel, advertising packets. The receiver determines a corresponding signal quality value and selects, for each data channel, an antenna from the antenna set on the basis of the determined signal quality values.
