Abstract

How to precisely detect co-channel narrow band interferences using single threshold is a challenge for satellite transponder spectrum monitor, especially in the condition of many signals which parameters are different. A new method for interference detection in satellite communication is proposed based on mathematical morphology. The paper uses an improved morphological gradient filter which belongs to image and graphics filed to deal with the spectrum data that is viewed as one-dimensional gray-scale image, and then search the gradient of interference edges to detect the position of it. Simulation results show that the proposed method can detect interference at one time when there are different signals with interference; it has not effect by the non-flat noise floor and has low computational complexity, is suitable for real spectrum monitor in satellite communication system
