The quality of channel state information (CSI) plays a significant role in the performance of
relay selection (RS) schemes in cooperative communications. Particularly in a highly mobile …

Cooperative communication has the potential of providing better throughput and reliability to
wireless systems when compared with direct communication. To realise the potential gain, it …

In this paper, we study relay selection under outdated channel state information (CSI) in a
decode-and-forward (DF) cooperative system. Unlike previous researches on cooperative …

In opportunistic selection (OS)-based systems, outdated channel state information (CSI) is
encountered due to channel variation between the instants of channel estimation and actual …

Relay selection has been considered as an effective method to improve the performance of
cooperative communication. However, the channel state information (CSI) used in relay …

Consider the scenario of relay selection in an environment where the channel estimates are
outdated, yet their reliability is known. For this scenario, we propose the optimal relay …

In this study, the authors investigate the outage‐optimal relay strategy under outdated
channel state information (CSI) in a decode‐and‐forward cooperative communication …

In this paper, we propose a relay selection method in an amplify-and-forward (AF) scenario
considering complete outdated channel state information (CSI) of all links. Differing from the …

It has been shown that cooperative communication can significantly improve performance by
utilizing distributed relay nodes. In most cases, cooperative communication systems have …

Relay selection has an important effect on improving the performance of cooperative
communication system. However, the frequent operation of relay selection can bring …
