Abstract

The invention relates to a device wake-up method and a wake-up receiver. The method comprises the following steps: receiving a wake-up signal; determining the same-direction signal duration of a same-direction signal segment between adjacent same-direction edges in the wake-up signal, wherein the adjacent same-direction edges are adjacent rising edges or adjacent falling edges; performing decoding according to the same-direction signal duration and the corresponding same-direction signal segment, and obtaining a target bit sequence corresponding to the wake-up signal; and when the target bit sequence contains a wake-up password for the target device, waking up the target device. By using the method, unable wake-up and false wake-up can be avoided.

Description

technical field [0001] The present invention relates to the field of communication technology, and in particular to a method for waking up a device and a receiver for waking up. Background technique [0002] The wake-up receiver is used for monitoring and receiving a wake-up frame for waking up the main circuit in a sleeping state when the main circuit with a strong communication function is sleeping. When the main circuit sleeps, its power consumption will be significantly reduced, but at this time, the communication connection of the main circuit will be interrupted. The longer the sleep time, the lower the overall power consumption. But only when the main circuit of the device wakes up from the sleep state can it complete its function. However, due to noise or loss in the signal transmission process, deformation occurs between the wake-up signal received by the wake-up receiver and the source signal, resulting in failure to wake up the device or waking up the device by m...
