不同混合波束形成系统的任意波束合成

Arbitrary Beam Synthesis of Different Hybrid Beamforming Systems

Kilian Roth, Josef A. Nossek

摘要:

对于未来的毫米波移动通信系统,模拟/混合波束成形的使用被设想为关键方面。波束合成是在波束搜索、数据传输和MU MIMO操作期间实现最佳可能操作的关键技术。所开发的合成波束的方法是基于以前的工作,在雷达技术只考虑相控阵天线。利用该技术,可以在期望的目标收发器天线前端的约束下生成任何形状的期望波束。它不受特定天线阵列几何形状的约束,但可以处理一维,二维甚至三维天线阵列几何形状,如圆柱形阵列。数值算例表明,该方法可以在增益、过渡区宽度和通带波纹之间进行用户自定义的折衷,实现波束综合。

英文摘要:

For future mmWave mobile communication systems the use of analog/hybrid beamforming is envisioned be a key as- pect. The synthesis of beams is a key technology of enable the best possible operation during beamsearch, data transmission and MU MIMO operation. The developed method for synthesizing beams is based on previous work in radar technology considering only phase array antennas. With this technique it is possible to generate a desired beam of any shape with the constraints of the desired target transceiver antenna frontend. It is not constraint to a certain antenna array geometry, but can handle 1d, 2d and even 3d antenna array geometries like cylindric arrays. The numerical examples show that the method can synthesize beams by considering a user defined tradeoff between gain, transition width and passband ripples.
