A diversity switch combiner for use in systems for receiving multi-carrier wideband signals is arranged to determine, during a guard interval, which antenna provides the strongest carrier, for each of a plurality of carrier frequencies. A switch is then operated to select, for the subsequent symbol, that antenna which provides the greatest number of strongest carriers.

Diversity switch combiner

A diversity switch combiner for use in systems for receiving wideband signals is arranged to split the received signal into separate channels each carrying a respective frequency band. Respective switch means are provided for each channel in order to switch the input of each channel between different antennas. A switch control determines the switch setting in accordance with the result of a comparison operation, preferably performed during a guard period, in which the signal qualities for different settings are compared.
