This paper presents a low-cost switched diversity receiver system utilizing a single tuner, simple remote antenna unit and one RF cable. The switched diversity algorithm is implemented in the receiver using digital signal processing. The remote unit contains RF switches that select from multiple antenna elements in response to a control signal from the receiver. The control signal is sent from the receiver to the remote unit via the RF cable. Simple logic in the remote unit provides decoding for switch control.
