TL;DR: Results show that partially-coherent receiver presents a similar performance to mismatched-receiver for sufficiently large loop SNRs although channel amplitude is completely ignored, and a second order diversity order is obtained for the considered single-relay scenario indicating that full diversity is extracted.

TL;DR: This paper investigates a cooperative system with multiple relays and amplify-and-forward relaying over frequency-selective channels, and demonstrates that PEP is not a simple exponential function of the signal-to-noise ratio (SNR), but it includes a term that involves some power of logarithm of the SNR.

TL;DR: This paper derives a closed-form expression for the bit error rate (BER) of the FSO link in such conditions when the on-off keying (OOK) modulation is employed and when the fluctuations of the received signal are modeled by Gamma- Gamma distribution.

TL;DR: This paper investigates the performance of a single-relay cooperative scenario where the source, relay and destination terminals are equipped with multiple transmit/receive antennas and quantifies analytically the impact of multiple antenna deployment for each relaying technique under various scenarios which involve relay location and power control assumptions imposed on cooperating nodes.

TL;DR: This paper investigates the performance of an amplify-and-forward (AF) cooperative diversity system with multiple relays in the presence of channel estimation errors and derives closed-form expressions for error probability, outage probability, and ergodic channel capacity.
