Co-site electromagnetic interference troubleshooting and validation of suppressing performance by extrapolation method

Co-site interference is becoming an increasingly significant problem in electronic systems. Ever increasing demand for more sophisticated, higher performance communication systems on one hand and the need for high density integrations in congested electromagnetic environments on the other have introduced numerous challenges to system designers. In this paper, the procedure of troubleshooting interference from vehicle to co-site radio system is detailed, and an approach for suppressing the interference is proposed. With the equivalent experiment and extrapolation method, the efficacy of suppressing is easily and effectively predicted. Also the signal coverage test and error analysis of prediction are reported.
