Diversity receiver

DETAILED DESCRIPTION It is an object of the present invention to provide a diversity receiver wherein the drawbacks of the conventional techniques are removed, power consumption is reduced, and quality of communication is improved.
The diversity receiver according to the present invention comprises: first and second receivers having receiver antennas and generating demodulated signals and electric field detection outputs in accordance with received electric fields, respectively; a first switch for switching between the demodulated signals from the first and second receivers in accordance with an output switching control signal and outputting a selected one of the demodulated signals; comparing means for comparing the electric field detection outputs from the first and second receivers, respectively, and supplying the output switching control signal to the first switch in accordance with the result of the comparison; a second switch for turning on/off a power supply source of the first receiver in accordance with a power source switching control signal; and a controller for receiving the electric field detection output from the second receiver, averaging intensity of the received electric field, and supplying the power source switching control signal to the second switch in accordance with the average intensity of the electric field.
