摘要
Abstract
With the rapid development of aviation communications and the increasing number of airborne terminals ,it is highly demanded to build up air to air wideband ad hoc networks supporting ultra high‐speed mobility both in civil and military aviation systems .Here ,the present situation and the develop‐ment trend of aviation communication networks are briefly outlined .On the basis of it ,the challenging issues of constructing such networks are presented ,including the support of ultra high speed mobility , high data transmission rate ,long distance single‐hop links ,large‐scale Ad hoc networking ,multiple user access mechanism ,as well as their restricted relationship .Finally ,physical layer key technologies and the related research progress for wideband airborne Ad hoc networks are reviewed ,including modulation technology ,peak to average power ratio suppression in OFDM ,frequency offset estimation ,channel esti‐mation and channel modeling .关键词
