Abstract
A radio receiver system for receiving double sideband signals from a plurality of antennas (N1,N2) having different reception characteristics detects a reduction in power in one of the sidebands of a received signal, due to multiple path reception or other disturbances. The system then selects for use by the receiver a signal from an antenna less affected by the disturbances.
Claims5
A radio receiver system comprising:
- a radio receiver for receiving double sideband signals applied to an antenna terminal of the receiver;
- at least two attennas having different reception characteristics;
- a switching arrangement arranged to connect the antenna terminal of the receiver to a selected one of the antennas;
- and control means for controlling the operation of the switching arrangement in dependence on the difference in power in the two sidebands of a signal at said antenna terminal.
