TL;DR: The results reveal that the selection of the closest transmitters to the receivers provides better performance due to high signal-to-noise-ratio requirements for RC mode whereas SM suffers from channel correlation.

TL;DR: Analytical performance results for space-time trellis codes over spatially correlated Rayleigh fading channels are presented and bit-error-probability estimates are obtained based on the derivation of an exact pairwise error probability expression using a residue technique combined with a characteristic function approach.

TL;DR: This tutorial provides a contemporary overview of HF communication and discusses cooperative diversity as an enabler to support the challenging expectations of future-generation HF communication systems.

TL;DR: In this paper, the performance of an UAV-based free-space optical relay system with amplify-and-forward relaying is analyzed under a general condition that takes into account the effects of nonzero boresight pointing errors along with the effect of orientation and position fluctuations of the UAV relay, the position with respect to the source and destination nodes, the optical beamwidth, turbulence strength of both source-to-relay and the relayto-destination links.

TL;DR: This paper considers a cooperative diversity system with orthogonal cooperation protocol and use DC-biased optical OFDM as the underlying physical layer and investigates the error rate performance of the proposed relay-assisted OFDM UV system under consideration and demonstrates performance gains over point-to-point OFDMUV systems.
