Abstract
An antenna diversity receiver with a variable delay time for antenna switching is disclosed. The antenna diversity receiver includes an antenna selective switching means for coupling one of a plurality of antennas to a RF receiver input. A multipath detector controls the antenna selective switching means. A switching disabling means automatically disables the antenna selective switching means over a disabling period. In order to accurately immunize the receiver the disabling period is controlled by an adjacent channel detector to increase the period with increasing adjacent channel interferences and to decrease the period with descreasing channel interferences.
