Reduced-Rank Channel Estimation for Large-Scale MIMO Systems
Ko-Feng Chen, Yen-Cheng Liu, Yu T. Su
We present two reduced-rank channel estimators for large-scale multiple-input, multiple-output (MIMO) systems and analyze their mean square error (MSE) performance. Taking advantag…
Detection of Spatially-Modulated Signals in Doubly Selective Fading Channels With Imperfect CSI
Hsuan-Cheng Chang, Yen-Cheng Liu, Yu T. Su
To detect spatially-modulated signals, a receiver needs the channel state information (CSI) of each transmit- receive antenna pair. Although the CSI is never perfect and varies in…
Composite Channel Estimation in Massive MIMO Systems
Ko-Feng Chen, Yen-Cheng Liu, Yu T. Su
We consider a multiuser (MU) multiple-input multiple-output (MIMO) time-division duplexing (TDD) system in which the base station (BS) is equipped with a large number of antennas f…
New Constructions of Zero-Correlation Zone Sequences
Yen-Cheng Liu, Ching-Wei Chen, Yu T. Su
In this paper, we propose three classes of systematic approaches for constructing zero correlation zone (ZCZ) sequence families. In most cases, these approaches are capable of gene…
