ASDR Technique for Signal Detection of Communication Equipment
Abstract— With the increase in the number of wireless signal transmitting equipment in East China, we urgently need a universal, real-time system to monitor the signal of the equipment in an all-round and full-time manner. At present, the main detection means of wireless signal transmitting equipment is to use the monitor of the equipment itself and the equipment such as outfield tester and spectrometer, which are single-function and expensive, and cannot meet the real-time monitoring and multi-point monitoring. In this paper, we propose to use software-defined radio (SDR) technology for signal detection of communication equipment. By studying the demodulation technology of SDR, the signal transmitted by the communication equipment is collected, analyzed, and processed, so as to get the relevant important parameter information of the equipment and ensure the accuracy of the transmitted wireless signal. Finally, this paper will verify the feasibility of SDR technology in signal detection of communication equipment through actual cases.
