Abstract: The number of connected wireless devices and the amount of generated digital information continue to grow exponentially, which create challenges in data acquisition, processing, transfer, and storage. For instance, in wireless communications, we are forced to shift our attention to newer frequency bands and rely on large antenna arrays to support many more users and the increased demand, creating challenges to incumbent users and increasing signal interference. At the same time, in digital storage, Moore’s law no longer holds, and we are investigating new possibilities such as storing data in DNA molecules.

In this talk, we will present our theory-hardware co-design approach to the ever-increasing challenges of data networks. We will talk about unique joint hardware-algorithm designs for spectrum management and investigate the theoretical limits as well as practical implications. We also present new findings and channel models for out-of-order media such as macromolecular storage and frame the problem as coded sequence assembly. We will discuss the potential impact of the findings on other domains such as 3D printing and rank aggregation.
