Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a wireless signal transmitting and receiving antenna system, a coupling amplifier and a signal processing method. Background technique [0002] With the continuous development of wireless networks, 3G and 4G technologies, existing wireless communication networks have higher and higher requirements for coverage, transmission bandwidth and anti-interference capabilities. At present, the method of expanding the coverage of wireless communication networks is mainly to increase the transmission power of the base station. However, increasing the base station's transmit power to a certain level in a two-way communication system cannot increase the coverage of the base station, mainly due to the limitation of the transmit power of the terminal equipment. Since the transmit power of the terminal equipment is designed considering the life of the battery and the impact on human health...

AI Technical Summary

Problems solved by technology

Since the uplink signal sent from the terminal equipment is seriously attenuated after being transmitted by the feeder cable of the antenna distribution system, the signal-to-noise ratio of the uplink signal reaching the base station is still very small, so that it is impossible to realize the communication between the base station and the terminal equipment in the wireless communication network. good communication
