摘要

我们提出了一种在分布式天线阵列中实现频率一致性的分散方法，该方法考虑了节点之间半双工无线协调的影响。在分布式天线阵列中的分离元件之间达到公共频率对于分布式波束形成是必要的，并且在不存在单点故障的情况下以分散的方式有益地实现。在这项工作中，我们提出了一种基于八卦的随机半双工(定向)算法，并证明了在100次迭代中，大小为5、20和100个节点的数组收敛到公共频率。

Frequency Consensus for Distributed Antenna Arrays With Half-Duplex Wireless Coordination

We present a decentralized approach for achieving frequency consensus in distributed antenna arrays that considers the effects of half-duplex wireless coordination between nodes. Reaching a common frequency among the separate elements in a distributed antenna array is necessary for distributed beamforming, and is beneficially implemented in a decentralized manner where no single point of failure exists. In this work we present a gossip-based randomized half duplex (directed) algorithm and demonstrate convergence to a common frequency for arrays of size 5, 20 and 100 nodes within 100 iterations.
