Space-Time Coded Cooperative Diversity with Multiple-Antenna Nodes

Abstract: In this paper, we investigate the performance of a single-relay cooperative scenario where the source, relay and destination terminals are equipped with multiple transmit/receive antennas. We assume conventional space-time block codes are employed in the underlying source-to-destination (S rarr D), source-to-relay (S rarr R) and relay-to-destination (R rarr D) links and consider both decode-and-forward (DaF) and amplify-and-forward (AaF) relaying techniques. Through the derivation of pairwise error probability (PEP), we quantify analytically the impact of multiple antenna deployment for each relaying technique under various scenarios. We further present an extensive Monte Carlo simulation study to corroborate the analytical results and to provide detailed performance comparisons among the relaying techniques under consideration.

Fundamentals of Coherent Optical Fiber Communications

Abstract: The recently developed digital coherent receiver enables us to employ a variety of spectrally efficient modulation formats such as $M$ -ary phase-shift keying and quadrature-amplitude modulation. Moreover, in the digital domain, we can equalize all linear transmission impairments such as group-velocity dispersion and polarization-mode dispersion of transmission fibers, because coherent detection preserves the phase information of the optical signal. This paper reviews the history of research and development related to coherent optical communications and describes the principle of coherent detection, including its quantum-noise characteristics. In addition, it discusses the role of digital signal processing in mitigating linear transmission impairments, estimating the carrier phase, and tracking the state of polarization of the signal in coherent receivers.
