Embodiment Construction
[0028] In order to improve the anti-interference performance of the equipment, an interference suppression solution can be adopted. The interference suppression scheme mainly includes two categories: 1) Scanning in a specific working state (such as module A working, module B not working; or module A running code stream Pattern_A, module B running code stream Pattern_B, etc.) through the RF probe Chip interference, according to the size of the interference, put forward the chip PCB layout requirements / add a shielding cover to achieve interference suppression. The limitation of this solution is that the efficiency is extremely low, and there is a high possibility of interference omission risk. 2) Interference suppression is realized by adding interference identification and suppression circuits in the radio frequency circuit. The limitation of this solution is that it will greatly increase the hardware cost and complexity, and the possibility of application in product scale desig...

The embodiment of the invention provides an interference suppression method and device. The method comprises the steps of: controlling equipment to operate in a plurality of interference states, and monitoring wireless transmission cache states of the equipment when the equipment operates in the plurality of interference states, the plurality of interference states comprising a first interferencestate in which a single interference source in the equipment works, and a second interference state in which a plurality of interference sources in the equipment work at the same time; determining interference levels according to the wireless transmission cache states when the equipment operates in the plurality of interference states, and determining a first corresponding relationship between theplurality of interference states and the interference levels; and determining an interference suppression mode for the plurality of interference sources in the equipment according to the first corresponding relationship, and performing interference suppression on the plurality of interference sources based on the interference suppression mode. According to the invention, the problem of how to improve the anti-interference performance of the equipment is solved, and the effect of enhancing the wireless performance is further achieved.
Description
technical field [0001] Embodiments of the present invention relate to the communication field, and in particular, to an interference suppression method and device. Background technique [0002] Any new wireless communication technology must be guaranteed by new radio frequency technology to convert digital signals into analog signals, and transmit data loaded with specific information into space for transmission through antennas. Wireless transmission is composed of a signal transmitter and a receiver. The transmitter transmits the modulated energy at a certain power. After space attenuation, it is received by the receiver at the receiver. The receiver can capture the signal with extremely small energy and demodulate it to restore the data. [0003] The fifth generation (The 5 th Generation, referred to as 5G) mobile communication compared with the fourth generation (The 4 th Generation, referred to as 4G) mobile communication, achieves the purpose of reducing delay and i...
