Slope‐based detection scheme for molecular communication systems
IET Communications, 2022 Improving data rate in the presence of the inter‐symbol interference (ISI) is one of the main challenging issues in molecular communication via diffusion‐based (MCvD) systems. In this paper, a slope‐based detection scheme is proposed, which acts based on

DMT analysis and optimal scheduling for FSO relaying communications
IET Communications, 2021 In this paper, two‐hop parallel N‐relay networks are considered and the diversity‐multiplexing tradeoff (DMT) is derived over Gamma‐Gamma free‐space optical (FSO) channels with identical average received signal to noise rations in all links.

Throughput‐based energy and spectral efficiency tradeoff for massive MIMO systems
IET Communications, 2021 In massive MIMO systems, energy efficiency (EE) and spectral efficiency (SE) can be balanced by tuning the number of the transmit antennas and the transmit power. However, two key parameters i.e.
