Abstract

An embodiment of the invention provides a mobile terminal motion state determining method and a mobile terminal motion state determining device. The mobile terminal motion state determining method comprises the steps of: acquiring electromagnetic wave signals received by a mobile terminal at at least two moments; and determining attitude variation of the mobile terminal at least according to channel characteristics and direction of arrival estimation of the electromagnetic wave signals received by the mobile terminal at the at least two moments. The method and the device provided by the invention can complete the determination of a motion velocity of the mobile terminal according to the multi-path electromagnetic wave signals received by the mobile terminal based on the multipath propagation transmitting feature of the received signals of the mobile terminal, and are high in precision.

Description

technical field [0001] The embodiments of the present application relate to the field of wireless communication technology and radio speed measurement, and in particular to a method and a device for determining the motion state of a mobile terminal. Background technique [0002] Mobile terminals are developing at a high speed in the direction of intelligence. With the improvement of user experience requirements, the measurement related to the movement of mobile terminals (such as movement speed measurement, posture change measurement and movement trajectory measurement, etc.) Essential functions, now mostly use miniaturized hardware modules such as gyroscopes and accelerometers to realize terminal motion-related measurements. However, due to the limitations of technology and the volume of terminal equipment, coupled with the complex surrounding environment in mobile scenes, such hardware modules are easily affected by the surrounding magnetic field and the accuracy is often ...
