Single-Carrier-Detection-Based Wake-Up Receiver Via Compressive Sensing

We designed a new single-carrier-detection-based wake-up receiver (SCD WuR), which can noncoherently detect a single carrier in a wide bandwidth with a small number of samples. The closed-form expression of the detection error rate of the SCD WuR is derived and validated. The performance of SCD WuR is also evaluated in terms of the minimum detectable signal-to-noise ratio, the power, and the wake-up time.
