Optimum MIMO-OFDM Receivers with Imperfect Channel State Information [PDF]
IEEE GLOBECOM 2008 - 2008 IEEE Global Telecommunications Conference, 2008 Channel estimation inaccuracy is known to affect significantly the error performance of coded communication systems. This applies in particular to broadband MIMO channels, often considered in conjunction with OFDM such as in the IEEE 802.11n and 802.16 standards.

Secrecy Enhancing Scheme for Spatial Modulation Using Antenna Selection and Artificial Noise
Entropy, 2019 In this paper, we present a new secrecy-enhancing scheme for the spatial modulation (SM) system, by considering imperfect channel state information (CSI). In the proposed scheme, two antennas are activated at the same time.

Joint Impact of Hardware Impairments and Imperfect Channel State Information on Multi-Relay Networks
IEEE Access, 2019 In this paper, we investigate the performance of dual-hop (DH) decode-and-forward (DF) multi-relay networks, for which two practical deleterious factors are taken into account, namely hardware impairments (HIs) and imperfect channel state information ...

Deep Learning-Based Secure MIMO Communications with Imperfect CSI for Heterogeneous Networks
Sensors, 2020 Perfect channel state information (CSI) is required in most of the classical physical-layer security techniques, while it is difficult to obtain the ideal CSI due to the time-varying wireless fading channel.
