Title:
GAIN COMPENSATION METHOD
Document Type and Number:
WIPO Patent Application WO/2021/023155
Kind Code:
A1
Abstract:
The present application relates to a gain compensation method, which is applied to a radio frequency transceiver, the radio frequency transceiver comprising a digital signal processing (DSP) module and a radio frequency (RF) module which are connected to one another. The method comprises: acquiring a working frequency band of an RF module; configuring a link of a DSP module as a frequency band which corresponds to the working frequency band of the RF module, and acquiring gain compensation data which is pre-saved in the DSP module and which corresponds to a working frequency band of the DSP module; and performing gain compensation on the DSP module by using the gain compensation data corresponding to the working frequency band of the DSP module. By configuring the link of the DSP module as the frequency band which corresponds to the working frequency band of the RF module, and performing gain compensation on the DSP module by using the gain compensation data which corresponds to the working frequency band of the DSP module, errors in gain compensation may be effectively reduced.
