Asynchronous Massive Connectivity with Deep-Learned Approximate Message Passing
ICC, pp. 1-6, 2020.
This paper considers massive connectivity in asynchronous systems, where a large number of devices sporadically send data to the base station (BS) with imperfect synchronization. Grant-free random access is considered and each device is assigned with a unique but not necessarily orthogonal pilot sequence for identification and channel est...More
