On the MIMO Capacity for Distributed System under Composite Rayleigh/Rician Fading and Shadowing

International Journal of Antennas and Propagation, 2015
Wireless channels are commonly affected by short-term fading and long-term fading (shadowing). The shadowing effects must be taken into account also when mobility is present in the wireless scenario.

Sensing-Assisted Secure Communications over Correlated Rayleigh Fading Channels

Entropy
We consider a secure integrated sensing and communication (ISAC) scenario, where a signal is transmitted through a state-dependent wiretap channel with one legitimate receiver with which the transmitter communicates and one honest-but-curious target that
