TL;DR: The physical layer secrecy performance of a hybrid satellite and free-space optical (FSO) cooperative system is studied and it is found that with the AF with fixed gain scheme, the secrecy diversity order of the investigated system is only dependent on the channel characteristics of the FSO link and theFSO detection type, whereas the secrecy Diversity is zero when the relay node employs DF or AF with variable-gain schemes.

TL;DR: The obtained results reveal the importance of taking the eavesdropper location uncertainty into consideration while designing V2V communication systems.

TL;DR: A comprehensive review of radio wave propagation in an industrial environment is presented, and reported channel models and measurement results of path loss, noise, interference, multipath propagation, and time-varying channel conditions are discussed.

TL;DR: An automated fall detection system based on smartphone audio features is developed and the best performance is achieved using spectrogram features with ANN classifier with sensitivity, specificity, and accuracy all above 98%.

TL;DR: The opportunities, challenges, and design principles of industrial wireless communication over the mmWave spectrum are discussed and performance analysis of mmWave industrial systems with respect to channel capacity is conducted using a realistic physical-statistical-based channel model.
