VI. CONCLUSIONS
We present two novel approaches to adaptive beamforming in satellite communications systems and compare them to the traditional GA. Our goal was to explore more efficient and real-time alternatives to GA, which, although effective, can be computationally expensive. Both approaches offer viable alternatives to GA for adaptive beamforming in satellite communication systems. These approaches not only reduce execution times but also maintain high system performance.
Selection between the two approaches should be based on the specific requirements of the application, taking into account the trade-off between classification complexity and overall system performance. As a result, these findings open up new possibilities for implementing efficient, real-time adaptive beamforming in wireless communication systems.
Future lines of research may include further optimizations of these approaches, exploration of hybrid models, or incorporation of additional features to improve performance and versatility.
