In this article, we study the advantages and disadvantages that full-duplex (FD) radio technology brings to remote-controlled drone counter-drone systems in comparison classical half-duplex (HD) technology. We consider especially physical-layer reliability perspective has not yet been comprehensively studied. For establishing a solid analytical background, first derive original closed-form expr...
In this letter, we consider the physical-layer security (PLS) in full-duplex (FD) multiuser multiple-input-multiple-output (MIMO) short-packet communications, where a base station (BS) transmits precoded signals for secure downlink multicast while receiving from uplink users. To quantify PLS performance worst-case scenario, possible maximum wiretapping capability of multi-antenna eavesdropper. ...
The advent of wireless communication technologies has created a paradigm shift in the accessibility of communication. With it has come an increased demand for throughput, a trend that is likely to increase further in the future. This has given rise to several challenges in developing new communication schemes. A key aspect of these challenges is to develop low complexity algorithms and architec...
the unique properties of air-cooled bainitic steels have been described. a series of mn containing air-cooled bainitic steels invented by authors is presented in this paper: including low carbon granular bainitic steels, low carbon grain-boundary allotriomorphic ferrite/granular bainite duplex steels, medium and medium high carbon bainite/martensite duplex steel, and low carbon carbide free bai...
This article offers the first characterisation of mixed Nash equilibria (MNE) for a wireless system with full-duplex capable terminals that share a common channel via Alohabased contention. Focussing on a simple grid topology, we prove that mixed MNE exist only if proportionality, driven by the accuracy of self-interference cancellation, is granted between the cost undergone for fulland half-du...
In this paper we address the sum rate maximization problem for a one-way amplify-and-forward relaying system with a full-duplex relay. This optimization problem which requires the joint source and relay precoding design is in general nonconvex. We propose different convex optimization based suboptimal schemes for different system settings. Moreover, we derive a gradient projection based algorit...
In Wireless communication systems, there are different types of transmission techniques or schemes are present. One of the important scheme is STBC, that is Space Time Block Codes. In STBC, different classifications are used. Most important one is OSTBC, Orthogonal Space Time Block Codes. As the name suggests the Orthogonal nature of this scheme is the main fame factor. Due to this nature ,we c...
