[2022] Wake-Up Receiver for Low-Power Internet of Things Applications

In many applications, the average data rate needed to transfer information gathered by sensors is much lower than the channel bandwidth. To save power, sensor data are gathered and sent periodically. The radio can be aggressively duty-cycled, and for only a small percentage of time is enabled to receive and send data. This can greatly reduce average power consumption, but the transceiver's time must align such that it is on at the same time as the node with which it must communicate. Wake-up receivers can coordinate such a data transfer. In this project, we aim to design and measure an extremely low-power but high interference-resilient wake-up receiver.
