摘要：
We survey our recent results on approaching the performance limits of wireless time-varying channels. In current practice, transceivers for such channels employ a large fraction of training or pilot overhead for channel estimation and tracking, together with coherent reception assuming that the channel estimates are accurate. In this paper, we discuss our progress in developing an alternative noncoherent approach, in which the channel and data are estimated jointly, heavily leveraging iterative decoding techniques.
