文中提出了一种适合于MIMO技术联合使用的零空间波束形成算法,该算法采用MIMO技术中常用的奇异分解方法,同时引入Gershman导数约束法来展宽波束零陷,既实现了增强期望,又能在干扰方向上形成较宽的零陷,增强了系统的鲁棒性。
This paper proposes a null space beamforming algorithm suitable for the joint use of MIMO technology. The algorithm uses the singular decomposition method commonly used in MIMO technology and introduces the Gershman derivative constraint method to broaden the beam null. It not only achieves the expectation of enhancement but also The formation of a wider null in the direction of interference enhances the robustness of the system.
