Effects of Channel Estimation on Spatial Modulation
2012
IEEE Signal Processing Letters
Preserved Fulltext
In this letter, we investigate the effects of trainingbased channel estimation on the achievable performance of the recent spatial modulation (SM) based multiple-input multiple-output (MIMO) scheme. ...
Our simulation results demonstrate that the SM scheme's BER curve exhibits a performance penalty, while relying on realistic imperfect channel-estimation. ...
Comparisons of the SM scheme's achievable BER performance between the three channel-estimation scenarios of the perfect CSI, the conventional training-based channel estimation and the joint channel estimation ...

Thus, we first develop a general model for D-MIMO systems, with a corresponding D-MIMO channel matrix, that forms the basis of the development in this paper. ...
A surprising result is that a quasi-coherent version of the underlying channel matrix can also be estimated from the D-MIMO matrix, making conventional linear interference suppression possible as well. ...
The D-MIMO system with perfect CSI is next in line, followed by the D-MIMO with estimated channel. The worst performance is that of D-MIMO without interference suppression. ...
