Ensuring reliable communication with low latency, is key to next-generation applications such as interactive voice and video, multiplayer gaming, multiplayer virtual reality and telesurgery. Not surprisingly, ultra-reliable low-latency communication is one of three focus areas of 5G cellular systems.
Our group has recently come up with a class of low-complexity, packet-level forward error-correction codes, termed as streaming codes. These codes maximize the rate of information transmission while maintaining robustness against a large class of packet-erasure patterns, under a stringent decoding-delay constraint. The packet erasures could arise for example, from dropped packets due to congestion in the network, or packets that are lost on account of a wireless link that is experiencing a deep fade. Our work has received recognition in the form of a paper  that was one of four finalists for the 2019 IEEE Jack Wolf ISIT Student Paper Award. It was also awarded a Qualcomm Innovation Fellowship 2019, India .
