Interference Diagnosis in Wireless Systems by using NI USRP

In both industrial and domestic environments, there will be a large increase of wireless communication systems. The density of wireless devices and need of additional bandwidth is expanding which is increasing the wireless interference. Interference emerges from unintended radiators is the main cause of degrading the Electromagnetic Compatibility and wireless communication performance in near field region and far field region and decrease the robustness and reliability. This paper presents methods of detection and removal of interference to improve EMC performance and wireless communication. We used NI USRP equipment for the diagnosis and provided the solutions to remove interference. The presented methods of interference diagnosis can efficiently optimize the performance of any wireless network.
