Abstract:
A proportional diversity radio system for a mobile vehicle having first and second space diversity antennas comprising:a first tuner for connecting to one of said antennas, said first tuner producing a first tuner output signal in response to a broadcast signal at a selected broadcast frequency, and said first tuner producing a first signal strength signal;a second tuner for connecting to the other one of said antennas, said second tuner producing a second tuner output signal in response to said broadcast signal at said selected broadcast frequency, and said second tuner producing a second signal strength signal;a proportional mixer combining said first and second tuner output signals to produce a mixed tuner output signal, said first and second tuner output signals proportionally contributing to said mixed tuner output signal in response to at least one mix control signal; anda mixer control detecting multipath distortion in each of said first and second tuner output signals caused by long-time-delay multipath conditions, said mixer control generating said mix control signal in response to said first and second signal strength signals and in response to said detected multipath distortion.
