Abstract:This paper presents the design of an algorithm to improve the detection of Bluetooth Low Energy advertising events in wake-up receivers. The goal is to decrease both latency and power consumption by reducing missed wake-ups and false wake-ups. The algorithm takes into account the Bluetooth Low Energy specifications including the packet length, packet interval, channel hopping, and a self-learning procedure of the advertising event interval. In the ideal case, the algorithm has a delay of 2 advertising events. Simulations show that in an environment with white Gaussian noise, the main receiver will wake-up consistently when required, with no false wake-ups, if the SNR is at least 0dB. Sensitivity can be sacrificed to decrease susceptibility to interference and noise power variations.
