Mobile data traffic grew by more than 50 percent between the first quarters of 2019 and 2020 is projected to grow close a factor 5 reach 164 exabytes per month 2025. This insatiable demand for mobile broadband communication services, including video, social networking, web browsing, audio, software updates, peer-to-peer file sharing, has been driven both rising number smartphone subscriptions i...

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...

Our research group at Yonsei University is working on the development of future wireless communications from theory to prototyping. We have collaborated with the NI advanced wireless research team through the RF/Communications Lead User Program since 2014. We demonstrated a real-time full-duplex LTE system at IEEE GLOBECOM in Austin, Texas, in December 2014. Based on this prototype, we can elab...

This paper discusses the distributed nature of airborne software intensive systems. The concept of fly-by-wire, the issues of safety, component communication, and certification are on the forefront of modern airborne applications. Since the communication between variety of onboard systems and subsystems is of paramount importance, the paper discusses the properties of new bus standard based on ...

Virtual full-duplex (VFD) is a powerful solution to compensate the rate loss of half-duplex relaying without the need to full-duplex capable nodes. Inter-relay interference (IRI) challenges the operation of VFD relaying systems. Recently, improper signaling is employed at both relays of the VFD to mitigate the IRI by imposing the same signal characteristics for both relays. To further boost the...
