A New Spatial Modulation Technology Based on Difference Equation

This paper proposes a new type of Spatial Modulation technology based on difference equations, which aims to explore a new anti-jamming transmission method in the airspace. The basic principle of the proposed system and the antenna mapping structure are introduced in this paper. The receiving algorithm is analyzed, and the performance difference with traditional Spatial Modulation is compared. Performance simulation shows that the system is slightly lower in anti-white noise performance than traditional Spatial Modulation technology, and the system performance can be improved by using a better antenna mapping structure. Also, the proposed system has a unique advantage in resisting intentional interference.
