Signal interference refers to unwanted disturbances or disruptions that occur in a communication system, causing a degradation in the quality or reliability of the signal being transmitted. This interference can come from a variety of sources, such as other electronic devices, electromagnetic radiation, or environmental factors. Researchers in the field of signal interference study ways to mitigate and control these disturbances in order to improve the overall performance of communication systems. This may involve developing algorithms, techniques, or hardware solutions to minimize the impact of interference on signal quality. Overall, the goal of research in signal interference is to enhance the efficiency, reliability, and security of communication systems in the presence of interference, ultimately ensuring better signal quality and transmission accuracy.
