Abstract
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.
