一种零陷波束赋型器的系统设计

System design of a null-steering beam-former

空分复用技术作为一种合理分配无线资源的方式,它依赖于自适应动态波束赋型技术以及高效算法(LMS,零陷等)。空分复用技术能够在不同的空域中同时重复利用相同频率资源。星间通信系统正朝着大容量、灵活性等方向发展,空分复用技术的出现可同时满足这些需求。本文主要研究在阵列天线系统下的零陷波束赋型技术。考虑到实际星间通信的场景,设计了一种零陷波束赋型器。

Spatial Division Multiple Access （SDMA） is a scheme of radio resource sharing that separates communication channels in space. It depends on adaptive and dynamic beam-forming technology and well-designed algorithms for users＇ allocation. As inter-satellite communication systems move towards a greater capacity, higher flexibility, SDMA appears to be one approach to satisfy these requirements simultaneously. This paper studies null-steering beam-forming technique in array antenna system. Considering virtual inter-satellite communication scenario, we design a beam-former to receive a signal of desired user.
