Synchronisation Issues in Non-coherent MIMO Systems

In this article, we identify some of the key problems that may be encountered when designing Non-Coherent (NC) Multiple-Input Multiple-Output (MIMO) DownLink (DL) synchronisation schemes for communicating over multi-path fading channels.

Multidimensional Parameter Estimation Method Based on Sparse Iteration in FDA-MIMO Radar

Leida xuebao, 2018
To accurately identify the range of each target, traditional Multiple-Input Multiple-Output (MIMO) radar techniques not only require designing a shift matrix to describe different range bins but also a large number of snapshots. To alleviate this problem,
