| Abstract(in English) | Recently, with the popularization of wireless IoT (Internet of Things), real-time spectrum monitoring technology for wireless IoT frequency bands (920 MHz band, 2.4 GHz band, 5-6 GHz band) is required to avoid the interference between different wireless IoT systems. We have proposed a direct RF undersampling receiver for wireless IoT real-time spectrum monitor using a clock switching scheme. It allows wider monitoring frequency bandwidth than 1/2 of the clock frequency (Nyquist limit) and real-time performance less than 1msec. In this report, we estimate the real-time performance of the proposed spectrum monitor and verify it by using a pulse pattern generator (PPG) as a high-speed variable clock source. |
