 ===Project: Fault-Tolerant LDPC Decoders=== ===Project: Fault-Tolerant LDPC Decoders===
-This research topic has attracted ​significant ​attention recently. My contributions have shown that we can accurately characterize the faults caused by occasional timing violations in the synchronous processing units of a decoder. This characterization can then be used to predict the performance of a faulty decoders for hypothetical infinite-length LDPC codes but also for finite-length codes. Finally, the use of faulty circuits reduces energy consumption __for the same quality of output__.+Error-correction codes (and particularly capacity-approaching codes like LDPC codes) are used to dramatically reduce the signal power on a communication link, but powerful codes also typically require a significant ​amount of energy to be decoded at the receiverIt is therefore highly desirable to reduce the energy consumption of such powerful ECC decoders, particularly in the context of IoT and sensor networks applications where both the transmitter and the receiver might be ultra-low power devices.
