Training Sequence Design for MIMO Channels: An Application-Oriented Approach
Dimitrios Katselis, Cristian R. Rojas, Mats Bengtsson +5
In this paper, the problem of training optimization for estimating a multiple-input multiple-output (MIMO) flat fading channel in the presence of spatially and temporally correlate…
