Abstract

The invention provides a method and a device for adaptively calibrating transmitting power in a radio frequency front-end module based on a data driving algorithm for a wireless communication system.By converting a transmitting power calibration problem into a dynamic linearized model, the design of a control system is simplified. Compared with other power calibration methods, the calibration algorithm provided by the invention eliminates a modeling step, does not need to establish an accurate system model, and only needs input / output (I / O) measurement data of the system. Related experimentalresults show that by using the proposed calibration algorithm and device based on data driving, the transmitting power error of the device can be reduced from 1.5 dB to 0.25 dB or less.

Description

technical field [0001] The invention belongs to the field of wireless communication, and in particular relates to a data-driven radio frequency (RF) transmission power calibration method and device for a wireless communication system. Background technique [0002] Wireless communication systems generally have wireless transceivers for transmitting and receiving wireless signals. Wireless communication refers to long-distance transmission and communication between multiple nodes without transmission through conductors or cables, including various fixed and mobile and portable applications such as two-way radios, cell phones, personal digital assistants and wireless networking. Other examples of radio wireless communication are GPS, garage door remotes, wireless mice, etc. [0003] Most wireless communication technologies use radio, including Wi-Fi with a distance of only a few meters, as well as deep space networks. In a wireless communication system, various devices usuall...
