Abstract

The invention discloses a method and a device for correcting spectrum flatness. The method comprises the following steps: determining a spectrum flatness curve of a target signal; determining a compensation coefficient of a compensation filter according to the spectrum flatness curve; and correcting the target signal according to the compensation coefficient to obtain a corrected target signal. According to the invention, the technical problems that a spectrum flatness correction process is complicated and prone to errors due to the fact that spectrum flatness is obtained by sending single-tone signals for multiple times in related technologies are solved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for correcting frequency spectrum flatness. Background technique [0002] In wireless communication systems, signals generally cover a certain bandwidth, especially as people's demand for high data rate transmission services increases, modern communication systems tend to use larger and larger signal bandwidths. However, due to the non-ideal characteristics of actual hardware, the transmitter / receiver in communication does not have the same transmission response to signals of different frequency components, which will lead to signals with different frequencies but the same power. After passing through the hardware circuit, The resulting power may also vary. Therefore, in the test of broadband signals, it is necessary to measure the spectral flatness (Spectral Flatness), which is an important test item to reflect whether the hardware cir...
