智能无人系统中协作感知的任务导向无线通信
Abstract—Collaborative Perception (CP) has shown great potential to achieve more holistic and reliable environmental perception in intelligent unmanned systems (IUSs). However, implementing CP still faces key challenges due to the characteristics of
the CP task and the dynamics of wireless channels. In this article,
a task-oriented wireless communication framework is proposed
to jointly optimize the communication scheme and the CP
procedure. We first propose channel-adaptive compression and
robust fusion approaches to extract and exploit the most valuable
semantic information under wireless communication constraints.
We then propose a task-oriented distributed scheduling algorithm
to identify the best collaborators for CP under dynamic environments. The main idea is learning while scheduling, where the
collaboration utility is effectively learned with low computation
and communication overhead. Case studies are carried out in
connected autonomous driving scenarios to verify the proposed
framework. Finally, we identify several future research directions.
