Immersive Media Streaming
Internet traffic used to send and receive video accounts for 82% of global traffic. Therefore, studying how to efficiently send and receive video data is very important. In particular, since most users watch video content through OTT platforms such as Netflix and YouTube, we study the service structures and signaling methods of MPEG DASH (Dynamic Adaptive Streaming over HTTP) and Apple HLS (HTTP Live Streaming) used in the above platforms.
Coding Schemes for 5G URLLC
Ultra-reliable and Low-latency Communication (URLLC) is an indispensable use case of the 5G mobile communication system. In particular, URLLC is an enabler of applications that are sensitive to latency as well as the reliability of communication, such as autonomous vehicles, manufacturing automation, and so on. Therefore, we study source coding, network coding, channel coding, and modulation schemes suitable for 5G URLLC.
Software-Defined Radio (SDR)
Software-Defined Radio (SRD) is being considered as a method to implement an Open Radio Access Network (O-RAN), that allows users to build their wireless networks. Therefore, we are employing GNU Radio, a free software development toolkit that provides signal processing blocks to implement SDR, to define and test the various coding schemes in SDR devices such as NI USRP and LimeSDR.
