A New Approach to Low-Power and Low-Latency Wake-Up Receiver System for Wireless

Abstract

A new wake-up receiver is p roposed to reduce energy consumption and latency through adoption of two diff erent data rates for the transmission of wake-up packets. To reduce the en- ergy consumption, the start frame bits (SFBs) of a wake-up packet are transmitted at a low data rate of 1 kbps, an d a bit-level duty cycle is employed for detection of SFBs. To reduce both energy con- sumption and latency, duty cycling is halted upon detection of the SFB sequence, and the rest of the wake-up pa cket
