Decoding-based channel estimation for selective cooperation diversity protocols
— We describe and analyze Minimum Path Difference (MPD), a metric to improve threshold-based Selection Decodeand-Forward (SDF) protocols in cooperative wireless networks with cha...

STBC MIMO OFDM Systems with Implementation Impairments
Multi-input multi-output (MIMO) systems are often realized with low cost front-end architectures, e.g. the so called direct conversion architectures. However, such systems are ver...

Beamforming design for multi-user two-way relaying with MIMO amplify and forward relays
Relays represent a promising approach to extend the cell coverage, combat the strong shadowing effects as well as guarantee the QoS in dense networks. Among the numerous existing ...

Large-Girth Nonbinary QC-LDPC Codes of Various Lengths
In this paper, we construct nonbinary quasi-cyclic low-density parity-check (QC-LDPC) codes whose parity check matrices consist of an array of square sub-matrices which are either ...
