Abstract: Methods and systems are provided for implementing a distributed algorithm for beam-forming (e.g., MVDR beam-forming) using a message-passing algorithm. The message-passing algorithm provides for computations to be performed in a distributed manner across a network, rather than in a centralized processing center or “fusion center”. The message-passing algorithm may also function for any network topology, and may continue operations when various changes are made in the network (e.g., nodes appearing, nodes disappearing, etc.). Additionally, the message-passing algorithm may minimize the transmission power per iteration and, depending on the particular network, also may minimize the transmission power required for communication between network nodes.

Abstract translation: 提供了使用消息传递算法实现用于波束形成（例如，MVDR波束形成）的分布式算法的方法和系统。 消息传递算法提供了以分布式方式跨网络而不是集中处理中心或“融合中心”执行的计算。 消息传递算法还可以用于任何网络拓扑，并且可以在网络中进行各种改变时（例如，出现节点，节点消失等）来继续操作。 此外，消息传递算法可以使每次迭代的传输功率最小化，并且根据特定网络还可以最小化网络节点之间的通信所需的传输功率。
