Problems solved by technology
However, the cost of high-speed ADC above 12bit is relatively high, so the 11bit ADC is widely used in practice.
[0004] 2. Use automatic gain control (AGC) to adjust the gain of the base station receiver. Automatic gain control (AGC) technology is one of the important technologies of communication receiving equipment. Due to the limitation of the number of bits of the analog-to-digital converter, the analog-to-digital converter alone cannot Provides a large receiving dynamic range
If the AGC is simply set to correspond to the strongest interference, the overall noise figure of the system will be greatly increased, resulting in the terminal having to transmit greater uplink transmit power to be able to communicate normally, resulting in a significant reduction in the coverage of the entire system
[0008] For the new wideband system, all in-band signals from heterogeneous systems are regarded as interference signals, and most narrowband signals have very strong power spectral density, while wideband signals have low power spectral density and are extremely vulnerable to narrowband Signal interference prevents it from working properly
Traditional power control technology does not consider heterogeneous interference factors, so it is no longer applicable

The invention relates to a wireless communication system, and discloses an anti-jamming method and an anti-jamming device for a wireless communication system. The method comprises the steps of receiving a radio frequency signal, analyzing the radio frequency signal to obtain the power change characteristic of the radio frequency signal, and determining a gain control method according to the power change characteristic of the radio frequency signal. According to the anti-jamming method and the anti-jamming device of the embodiment of the invention, the communication quality of the wireless communication system can be guaranteed under the condition of sudden strong interference.
Description
technical field [0001] The present invention relates to a wireless communication system, and more particularly to an anti-jamming method and device for the wireless communication system. Background technique [0002] The wireless communication system (Wireless Communication System) consists of three parts: sending equipment, receiving equipment, and wireless channels. It uses wireless electromagnetic waves to realize information and data transmission. Due to its great convenience in communication methods, wireless communication has been widely used. application. Cellular networking has become the main networking method for wireless communication due to its good coverage capability, reasonable network construction cost, and better utilization efficiency of spectrum resources. In a cellular network, the base station is the center of the cell and needs to communicate with all terminals in the cell. Since the distance between the base station and each terminal is different, an...
