Embodiment Construction

[0024] Such as figure 1 As shown, a method for reducing signal interference in a wireless communication integrated circuit includes the following steps:

[0025] S102: Obtain a wireless communication signal collected when the antenna of the wireless communication integrated circuit is turned on.

[0026] Specifically, the wireless communication integrated circuit is turned on, the antenna is turned on, and wireless communication signals are collected. The collected wireless communication signal is processed into an intermediate frequency signal after being mixed and amplified by the receiving circuit. The invention reduces the intermediate frequency interference in the wireless communication integrated circuit by processing the intermediate frequency signal.

[0027] S104: Perform spectrum analysis on the wireless communication signal to obtain a signal spectrum of the wireless communication signal.

[0028] Signal spectrum analysis is to expand the signal strength sent by ...

Abstract

The invention relates to a method and an apparatus of reducing a signal interference in a wireless communication integration circuit. The method comprises the following steps of acquiring a wireless communication signal collected when an antenna of the wireless communication integration circuit is started; carrying out frequency spectrum analysis on the wireless communication signal and acquiringa signal frequency spectrum of the wireless communication signal; comparing the signal frequency spectrum of the wireless communication signal with a signal frequency spectrum of each noise signal ina preset noise model, and determining a first interference signal in the wireless communication signal; according to the signal frequency spectrum of the noise signal which is most similar to the first interference signal in the preset noise model, generating a first offset signal which is opposite to the noise signal which is the most similar to the first interference signal; and processing the wireless communication signal and the first offset signal and acquiring a processed wireless communication signal. In the method, a device does not need to be added to carry out physical isolation on awireless communication circuit and a digital system circuit, and cost is low.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a method and device for reducing signal interference in a wireless communication integrated circuit. Background technique [0002] At present, with the rapid development of the Internet of Things and wearable technology, various electronic products have an increasing demand for SOC chips (systems on a chip) with integrated wireless communication functions, and at the same time have higher and higher requirements for wireless communication performance. But the wireless communication circuit, especially the receiving circuit, is very sensitive and fragile to various noise interference. The main interference sources of wireless communication circuits are digital systems and various clock signals. The interference of the digital system and various clock signals is transmitted to the intermediate frequency signal through the mixing, amplification and other paths of the r...
