The Diversity Potential of Relay Selection with Practical Channel Estimation
Diomidis S. Michalopoulos, Nestor D. Chatzidiamantis, Robert Schober +1
We investigate the diversity order of decode-and-forward relay selection in Nakagami-m fading, in cases where practical channel estimation techniques are applied. In this respect,…
Protocols for Relay-Assisted Free-Space Optical Systems
Nestor D. Chatzidiamantis, Diomidis S. Michalopoulos, Emmanouil E. Kriezis +2
We investigate transmission protocols for relay-assisted free-space optical (FSO) systems, when multiple parallel relays are employed and there is no direct link between the source…
Buffers Improve the Performance of Relay Selection
Aissa Ikhlef, Diomidis S. Michalopoulos, Robert Schober
We show that the performance of relay selection can be improved by employing relays with buffers. Under the idealized assumption that no buffer is full or empty, the best source-re…
