Frequency control method and device for wireless communication system

Abstract

The invention discloses a frequency control method for a wireless communication system. The frequency control method comprises the following steps that a front end detecting device detects the working frequency of a transmitter, and a back end control device detects the working frequency of a receiver; the front end detecting device obtains the working frequency of the receiver, and judges whether the working frequency of the transmitter is the same as that of the receiver or not; if so, the transmitter and the receiver establish wireless communication; and otherwise, the back end control device adjusts the working frequency of the receiver to be the working frequency of the transmitter. The invention further discloses a frequency control device for the wireless communication system, comprising N transmitters, N front-end detecting devices, the receiver and the back end control device, wherein N is more than or equal to 1. The frequency control method and device for the wireless communication system provided by the invention can be used for controlling the working frequency of the receiver, so that the quantity of the receiver and related assorted equipment can be effectively controlled, and the use ratio of system resources can be improved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method and device for controlling frequency of a wireless communication system. Background technique [0002] Wireless communication (Wireless Communication) is a communication method that uses the characteristics that electromagnetic wave signals can propagate freely in space to exchange information. In recent years, wireless communication technology has developed the fastest and is most widely used in the field of communication technology. [0003] Existing wireless communication systems mainly include: mobile cellular network systems, wireless local area network systems, radio and television systems, satellite communication systems, and some short-distance wireless communication networks. Among them, the mobile cellular network system mainly includes the Global System of Mobile Communication (GSM for short) of the second generation mobile communicatio...

AI Technical Summary

Problems solved by technology

When the scale of the wireless communication system is large, the number of transmitters at the front end of the system continues to increase, and the back-end command center will have a large number of receivers and related equipment, which also makes the structure of the wireless communication system too complicated

[0008] Therefore, the current wireless communication system generally has defects such as complex structure, low resource utilization, serious frequency interference and high construction cost.
