This paper introduce Fractional Delay Filter (FD) into SelfInterference Cancellation based Full-Duplex communication system. The paper explains that an accurate delay of baseband signal in cancellation channel is very important for the performance of self-interference cancellation. It emphasise that a delay other than a phase alignment can extend the cancellation to wideband with reasonable per...

Radio communication, one of core contents in wireless communication, is facing a great crisis of running out of resource. Unlike other energy crisis which can be solved by using all kinds of alternative energy, the only resource of radio communication is channel, in another word, spectrum. Rather than sticking on trying to achieve the rest one percent of capacity, more and more scholars start t...

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...

Relay cooperation can enhance coverage, throughput, and reliability of wireless communication systems, thus attracting intense research interest in the past decade. However, most of them focused on half-duplex relay systems, which encounter loss of resource efficiency. With the progress of self-interference cancellation technologies, full-duplex relay systems come into sight. In this paper, out...

Device-to-device (D2D) pairs are allowed to reuse the spectrum of cellular users who are in a good quality channel state with underlaying cellular network. However, cellular users usually suffer a poor performance in term of achievable rate when they are in a cell edge or in deep fading. To solve this problem, a hybrid relay-aided D2D communication scheme with a two-antenna infrastructure and u...

This paper investigates the passive beamforming and deployment design for an intelligent reflecting surface (IRS) aided full-duplex (FD) wireless system, where FD access point (AP) communicates with uplink (UL) user a downlink (DL) simultaneously over same time-frequency dimension help of IRS. Under this setup, we consider three cases: 1) two distributed IRSs placed near UL DL user, respectivel...

Wireless powered communication networks (WPCNs) will act as a major enabler of massive machine type communications (MTCs), which is service domain for 5G and beyond systems. The MTC be deployed by using low-power transceivers with finite discrete configurations. This paper considers minimum length scheduling problem full-duplex WPCNs, where users transmit information to hybrid access point at r...

In the neighbourhood gossiping problem, each node of a network starts with a unique message and must learn the messages of all of its neighbours. In this paper, we prove upper and lower bounds for neighbourhood gossiping in hypercubes under the single-port half-duplex and single-port full-duplex communication models.
