Abstract

A radio signal processing system includes a first antenna; a second antenna; a first receiver communicatively coupled to the first antenna; a second receiver communicatively coupled to the second antenna; a first processing unit communicatively coupled to the first receiver and configured to receive a first signal from at least one of the first antenna and the second antenna when the system is operating in a first mode; a second processing unit communicatively coupled to the second receiver and configured to receive a second signal from the second antenna when the system is operating in a first mode; and wherein the first processing unit is further configured to receive a third signal from both the first antenna and the second antenna when the system is operating in a second mode.

Claims9

Dependent claims

A radio signal processing system comprising:

a first antenna;
a second antenna;
a switch switchably coupling the first antenna and the second antenna to a wideband multi-channel receiver;
a processing unit communicatively coupled to the wideband multi-channel receiver;
wherein the processing unit is configured to receive both a first signal and a second signal from the first antenna through the wideband multi-channel receiver when the system is operating in a first mode and the switch is in a first position, wherein the first signal is an instrument landing system (ILS) mode localizer signal, wherein the second signal is a VHF Omnidirectional Range (VOR) signal;
wherein the processing unit is configured to receive both the first signal and the second signal from the second antenna through the wideband multi-channel receiver when the system is operating in the first mode and the switch is in a second position;
wherein the processing unit is configured to receive both a third signal and the second signal from the first antenna through the wideband multi-channel receiver when the system is operating in a second mode and the switch is in the first position, wherein the third signal is a VHF Data Broadcast (VDB) signal;
and
wherein the processing unit is configured to receive both the third signal and the second signal from the second antenna through the wideband multi-channel receiver when the system is operating in the second mode and the switch is in the second position.
