Abstract

Embodiments of the present disclosure provide a method, device, system, and medium for adjusting a transmission signal of an antenna, and relate to the technical field of antennas. The method includes: acquiring a coupled signal, and determining an adjacent channel leakage ratio ACLR of the coupled signal; the coupled signal is a first signal output by the transceiver after predetermined processing and then separated by a coupler, and the first signal is a signal in the transceiver. The analog signal converted from the digital signal to be transmitted. When the ACLR of the coupled signal is smaller than the preset target ACLR, digital filtering is performed on signals of the digital signal to be transmitted in adjacent channels, and the digitally filtered digital signal to be transmitted is used as a new digital signal to be transmitted. The embodiments of the present disclosure are used to solve the technical problems in the prior art that are easily limited by the debugging environment and the debugging process is complicated, and can transmit a transmit signal that achieves a preset effect and improve the performance index of the output signal.

Description

technical field [0001] The present disclosure relates to the technical field of antennas, and in particular, the present disclosure relates to a method, device, system and medium for adjusting a transmission signal of an antenna. Background technique [0002] When a device with an antenna transmits a signal, the transmitted signal includes the signal in the channel used for transmitting the signal and the signal in the adjacent channel of the channel. ACLR (Adjacent Channel Leakage Ratio, adjacent channel leakage ratio) refers to the transmission The ratio of the power to the power that falls on the adjacent channel, that is, the ratio of the signal power in the channel to the signal power in the adjacent channel. ACLR is an important test item, for example, a test item of an RF (Radio Frequency, radio frequency) indicator of a smartphone. [0003] At present, the debugging of the ACLR index of the transmitted signal mainly lies in the debugging of PA (Power Amplifier, powe...
