摘要： In accordance with various aspects of the disclosure, a system, method, and device for detecting motion based on channel fading characteristics are presented. One or more packets may be received wirelessly from a wireless transmitter. A fading profile may be determined for each packet. From the plurality of fading profiles, one or more parameters indicative of fading change, changes in shape of fading profiles, fading variance, and of other channel characteristics may be determined. A classifier function may be trained to associate parameter values with a lack of motion, with device motion, or with motion of an object in the vicinity of a stationary wireless-enabled device. The classifier function may be used to determine whether there is motion based on one or more subsequently received packets.

摘要翻译：根据本公开的各个方面，提出了一种基于信道衰落特性检测运动的系统，方法和装置。可以从无线发射机无线地接收一个或多个分组。可以为每个分组确定衰落简档。可以从多个衰落分布中确定指示衰落变化，衰落分布的形状变化，衰落方差以及其它信道特性的一个或多个参数。可以对分类器功能进行训练，以使参数值与运动的缺乏，设备运动或者在固定无线设备附近的物体的运动相关联。分类器功能可以用于基于一个或多个随后接收的分组来确定是否存在运动。
