Abstract: An information exchange apparatus of each node for sharing information between a plurality of nodes receives request information from an adjacent node and determines an information transmitting node based on information that each node holds and request information from the adjacent node. The information exchange apparatus of a node that is determined to be an information transmitting node generates candidate transmitting information by performing network coding of at least one information set of held information, determines one of the candidate transmitting information sets as transmitting information, and transmits the candidate transmitting information set to the adjacent node.
Abstract translation: 用于在多个节点之间共享信息的每个节点的信息交换装置从相邻节点接收请求信息，并且基于每个节点保存的信息并且从相邻节点请求信息来确定信息发送节点。 确定为信息发送节点的节点的信息交换装置通过执行至少一个保持信息的信息集的网络编码来生成候选发送信息，将候选发送信息集中的一个确定为发送信息，并发送候选 向相邻节点发送信息集。

Abstract: In a method of estimating a channel in a multicarrier system, a channel path is estimated if a signal is received through a multi-path channel. A channel is estimated based on the signal received from the estimated channel path. A compressive sensing-based channel estimate for repeatedly performing such path estimate and channel estimate is carried out.
