During the so-called happy scaling era of integrated circuits, the increasing transistor count per unit area and the increasing energy-efficiency were able to offset the ever-increasing complexity of communications and digital signal processing algorithms. Unfortunately, the gains from circuit technology scaling have slowed down significantly in the last few years. In this talk, I will present ways to ensure that the progress of the last decades is maintained, ranging from classical algorithm/hardware co-design to more interdisciplinary approaches. More specifically, I will first discuss the hardware implementation of successive cancellation list decoding and successive cancellation flip decoding of polar error-correcting codes (ECC), which were recently included in the next-generation 5G standard for wireless communications. I will then examine the use of approximate computing techniques to increase the throughput and energy-efficiency of ECC decoders and I will present the application of tools from information theory and machine learning to the design of Terabit/s ECC decoders and non-linear self-interference cancellation in full-duplex radios, respectively. Finally, I will conclude the talk by identifying some promising future research directions.
