Detailed description
Error-correction codes are used in the vast majority of communication systems because they allow a large reduction of the transmitter power, and therefore make it possible for a device (for example a connected object) to transmit a message with less energy. Unfortunately, good error-correction codes require significant energy to be decoded at the receiver, and there is therefore a tradeoff between the energy saved by the transmitter and additional energy spent by the receiver.
In this research project, we develop methods for designing error-correction codes and associated decoder systems that minimize the total energy spent by the transmitter and receiver. This is a challenging problem because there exist many ways to do error correction! To solve this problem, we must study both the energy consumption of the digital circuits that perform the error correction and the theory of error-correction codes.
Impact: This research will allow improving the energy efficiency of telecommunications and information storage technologies. For example, it will allow longer battery-life for remote sensors, reducing energy consumption in data centers, and even improving robustness and efficiency of memory circuits used by microprocessors.
