Proper relay selection (RS) plays a key role for improving the reliability of wireless networks,
especially in the presence of jamming attacks and/or interferers. In this work, we consider …

We consider about a multiple relay system operating under amplify-and-forward (AF)
protocol and non-coherent modulation and demodulation. When the relays are under long …

We consider an amplify-and-forward (AF) cooperative diversity network consisting of one
source, multiple relays, one destination, and multiple interferers. It is assumed that only …

In this paper, we investigate the physical layer discriminatory channel estimation (DCE) in
multiple-input multiple-output (MIMO) decode-and-forward (DF) relay systems which …

In this paper, we consider the bit error rate (BER) performance analysis of a cooperative
relay communication system with differential modulation and selective relaying, where the …

A relaying technique based on single-relay selection is studied for multiple-relay networks
when hierarchical modulation is employed for unequal error protection. A single-relay …

In this paper, we derive the Symbol Error Probability (SEP) of cooperative systems with
incremental relaying and Distributed Relay Selection (DRS). The relays remain idle when …

We investigate the physical layer security in non-regenerative untrusted relay networks,
where the relay is a potential eavesdropper despite its cooperatively relaying the …

In this correspondence, we introduce a new training protocol for channel state estimation in
wireless relay networks. The distinctive feature of our protocol is that each relay forwards the …

Cooperative diversity is a promising technology for future wireless networks. In this paper,
we consider a cooperative communication system operating in an amplify-and-forward (AF) …
