Claim of US Patent No. 9,083,413

1. A method for reducing interference between at least two adjacent antennas comprising a receiver equipment antenna and a
transmitter equipment antenna, comprising:
transmitting a first signal from the transmitter equipment antenna;
receiving the first signal at the receiver equipment antenna;
receiving a second signal at the receiver equipment antenna;
inputting the received first and second signals into a cross-polar interference canceller, included in the receiver equipment,
for processing;

calculating at least one of a respective power and a respective BER of the processed first and the second signals;
selecting, between the processed first signal and the processed second signal, the signal that has its respective power greater
than the respective power of the other signal, or the one that has its respective BER lower than the respective BER of the
other signal; or

selecting between the processed first signal and the processed second signal the signal that has its respective power greater
than the respective power of the other signal and has its respective BER lower than the respective BER of the other signal;

wherein the transmitter equipment antenna and receiver equipment antenna are installed adjacent to each other on a common
tower.
