Dual Receiver with Phase and Switched Diversity for Background Processing and Reception Improvement 2008-01-1059
This paper presents a cost-effective receiver system utilizing dual tuner antenna diversity. There are two modes of operation. In mode 1, the system is in phase diversity where two tuners operate harmoniously to minimize severe multipath distortion using beam pointing. In mode 2, the two tuners operate independently while still achieving reception improvement through intelligent antenna switching. This mode uses one tuner with two antenna switched diversity while the second tuner performs background processing. An advantage of this dual tuner architecture is the ability to provide concurrent multipath distortion reduction and background processing. An example of a digital FM receiver which embodies these functions is described.
