Patent ID: 8593330

Claim:
A method comprising: at a first receiver connected to a first antenna, receiving a signal from the first antenna; filtering the received signal based on bandwidths associated with a traffic collision-avoidance system (TCAS), a transponder, and a universal access transceiver (UAT); digitizing the filtered signal using a first analog-to-digital converter (ADC); and digitally downconverting the digitized signal into first TCAS signals, transponder signals, and UAT signals; and at a second receiver connected to a second antenna, receiving a signal from the second antenna; separating the received signal based on bandwidths associated with the TCAS, the transponder, the UAT, and distance measuring equipment (DME) (the DME bandwidth consisting of an upper half of a DME RF band and a lower half of the DME RF band) into a first signal having a bandwidth associated with the TCAS, the transponder, the UAT and the lower half of the DME RF band to produce a signal comprising a TCAS signal, a transponder signal, a UAT signal, and a lower half DME signal, and into a second signal having a bandwidth associated with the upper half of the DME RF band, the second signal comprising an upper half DME signal; digitizing the first and second signals using second and third ADCs, respectively; and digitally downconverting the digitized first and second signals into second TCAS signals, transponder signals, UAT signals, and upper and lower half DME signals.
