Abstract
A distributed antenna system of an aircraft includes first and second antennas and corresponding first and second remote transceiver units (RTUs). Each RTU receives a radio signal from the corresponding antenna and includes a field-programmable gate array (FPGA)/digital signal processor (DSP). The FPGA/DSP of a second RTU receives a second signal corresponding to the radio signal from the second antenna and receives a first signal from the first RTU corresponding to the radio signal from the first antenna. The FPGA/DSP of a second RTU determines which of the first and second antennae will transmit a reply to an interrogation included in the radio signals from the first and second antennae, based on a comparison of the first signal and the second signal.
