Mitigating Inter-satellite Interference in Dense LEO Satellite Networks

Inter-satellite interference is a significant issue that affects the performance of satellite systems. The signal-to-interference plus noise ratio (SINR) is a crucial indicator that determines the level of interference in a system. To mitigate this problem, various techniques can be employed.

Direct methods such as antenna design and electromagnetic wave cancellation can be used to reduce interference. However, studying the characteristics and parameters of a satellite system can also be crucial. Analyzing the interference of ultra-dense LEO satellite networks during motion and adjusting the constellation's orbit parameters can minimize the superposition of electromagnetic beams in space, thereby improving the overall system performance.

Furthermore, designing and optimizing the beams' parameters, such as beam width and direction, can reduce interference in the satellite system. Increasing the transmission power can also improve SINR, but it can cause greater interference to other signals. Therefore, choosing the appropriate signal power is crucial to improve SINR and increase the system's channel capacity.

By employing these techniques, inter-satellite interference can be minimized, resulting in a smoother and more efficient satellite system.
