Problems solved by technology

[0002] In the traditional microwave relay forwarding communication technology, the point-to-multipoint TDMA technology is usually used, and the data transmission rate is relatively fixed. Generally, the fixed data transmission rate communication is set according to the communication distance and the change of the communication environment. This communication method is relatively stable. However, the ability to change with the environment is poor, and the data transmission rate is fixed, the data forwarding speed is not high, cannot meet higher communication quality, the transmission rate conversion is complicated, and the adaptability to burst transmission is poor
[0003] In addition, the existing microwave forwarding system has serious self-interference and out-of-synchronization problems
