摘要：In recent years, attacks from pseudo base stations and other kinds of illegal wireless access have emerged one after another, and more and more telecom frauds are causing numerous property losses. There is an urgent need for real-time monitoring of the utilization of wireless spectrum, so as to identify illegal signals and take appropriate protective measures promptly. Traditional wireless spectrum monitoring solutions used to be narrow-band, and due to the insufficient capabilities of data acquisition equipment, the amount of equipment needed is huge, which will lead to the increase of cost, energy consumption and maintenance complexity. We need to transmit signals from various areas to a specific place, where there is a global and full-spectrum perception device that could process and analyze wide-band signals. Therefore, a wireless channel monitoring architecture is proposed and experimentally demonstrated. Based on microwave photonics, this architecture is consisted of an optical-wireless converged network and an all-optical channelized receiver. The frequency error of the channelized receiver is no more than 50 kHz, meeting the requirement for signal analysis in 5G communications. The experiment results show that the proposed architecture could effectively monitor collected signals of different channels.
