| Summary: | This research focuses on data collection for the entire East West Line as well as the North South Line. The experiment is carried out using discone antennas and the EM200 Spectrum Monitoring system. The experimental findings indicate that the 2.4GHz Industrial, Scientific, and Medical (ISM) Frequency band has a high level of spectrum occupancy. In this ISM frequency band, which is also occupied by the Communication Train Based Control (CBTC) system, various signals such as WiFi and CCTV can be found. As a result, the CBTC system is vulnerable to disturbances from nearby signals. As a result, machine learning algorithms are being used to help understand the different signals' characteristics. In addition, Image Processing techniques are applied to the different waterfall diagrams generated by the experiments. The goal is to find and mark the existence of signals in the diagram, as well as where they appear in the picture. |
