Abstract
A diversify receiver comprises an antenna selector for selecting signals received by diversity antennas. Detection circuitry detects respective strengths of the selected signals and produces first and second strength indication signals. A mode selector is provided for selecting a reference threshold or the second strength indication signal. A comparator compares the output of the mode selector with the first strength indication signal. The mode selector is controlled to select the reference threshold so that the first strength indication signal is compared with the reference threshold and then to select the second strength indication signal in response to a first output signal of the comparator indicating that the first strength indication signal is higher than the reference threshold, so that the first strength indication signal is compared with the second strength indication signal. The antenna selector is then controlled according to a second output signal of the comparator indicating the result of the comparison between the first and second strength indication signals.
