Research on the Performance of Multi-Antenna System Applied to Unmanned Communication Link
With the development of unmanned satellite communication links,signal attenuation,interference,and link reliability have become the focus of attention.Deeply explore the application of multi antenna systems in unmanned satellite communication links,analyze channel models and their interference,and further study the core principles of multi antenna systems,such as space-time coding and Multiple Input Multiple Output(MIMO)technology.Design protocols based on multiple antennas,emphasizing their importance in channel estimation and modulation coding.Experimental comparison shows that multi antenna systems are significantly better than single antenna systems in signal quality and transmission rate,but they still face hardware and compatibility challenges in practical applications.
