In this paper, we propose a geometric approach for optimal power control and relay
selection in NOMA wireless relay networks. First, for each pair of relays, to derive an optimal …

In this paper, we propose a relay selection method for cooperative communication systems
(CCS) employing the QPSK modulation scheme. The relay nodes forward their reliability to …

The performance of diversity combining based on the Data Quality Metric (DQM) is limited by
the challenges of accurately estimating the received Eb/N0 in the demodulator. This paper …

In this paper, a down-link cooperative communication scheme is proposed using full-rate
Quasi-Orthogonal Space-time Block Codes (QOSTBC), employing asynchronous mobile …

The 5th generation mobile networks are capable of processing large amounts of data from
the users. Cooperative communication is a novel method that enables single transmitters in …

In this paper, a Decode and Forward (DF) cooperative communication scheme, achieving
full rate, is introduced. The scheme uses Minimum-Decoding complexity Quasi-Orthogonal …

In the above named paper [ibid., vol. 61, no. 5, pp. 1776–1785, May 2013], the authors
correct an error from equation (12) and (13), on the variance of z given g and s that is …

Cooperative communication is regarded as a key technology in wireless networks, including
cognitive radio networks (CRNs), which increases the diversity order of the signal to combat …

During the last few decades, cooperative communication became one of the main research
domains in the communication field. The concept of cooperative communication through …
