The baseband modulated signal may refer to a signal carrying useful information, and the signal carrying useful information and easy to transmit is called a modulated signal; a radio frequency demodulated signal may refer to a message recovered from a modulated signal carrying information; the control signal can refer to signals such as operation, measurement, detection, action and control and the like sent by a control system to the controlled equipment; the system clock can refer to a high-performance processor clock system based on a CMOS process, the integrated PLL can be triggered from the inside, and the triggering is faster and more accurate than the triggering from the outside, so that problems related to signal integrity can be effectively avoided; a data link may refer to a telecommunications installation that connects two or more data stations according to the specifications of a link protocol.
It should be noted that the structure and function of the narrowband radio frequency unit are similar to those of the wideband radio frequency unit, and those skilled in the art can obtain the structure of the narrowband radio frequency unit with reference to fig. 3 to implement modulation and demodulation of the narrowband mobile signal, which is not described herein again.
The antenna feeder processing unit can realize the combination of a plurality of carrier frequency transmitting signals.

The antenna feed processing unit may provide a bidirectional path for the transmit band and the receive band from the antenna to the radio frequency processing unit.
In the embodiment of the present disclosure, both the antenna feeder processing unit in the broadband communication device and the antenna feeder processing unit in the narrowband communication device can simultaneously implement transmission and reception of signals.
The antenna feed processing unit can alarm when the standing wave ratio of the antenna port is deteriorated.
The Standing wave ratio is also called Voltage Standing Wave Ratio (VSWR). In radio communication, if the impedance of the antenna of the base station is not matched with that of the feeder line or the impedance of the antenna is not matched with that of the transmitter, a part of the emitted high-frequency energy is reflected and folded back, and is combined with the forward high-frequency energy interference to generate a standing wave, and the ratio of the maximum value and the minimum value of adjacent voltages of the standing wave is a standing wave ratio; if the standing-wave ratio is too large, the communication distance is shortened, and even the reflected power returns to the power amplification part of the transmitter, so that the power amplification tube is burnt out, and normal communication is influenced.
In the embodiment of the disclosure, the antenna feed processing unit can give an alarm when the standing-wave ratio of the antenna port is deteriorated, and can timely remind when communication is abnormal, thereby ensuring smooth communication.
In the embodiment of the disclosure, the antenna feeder processing unit may further suppress interference and stray radiation outside the operating frequency band.
In the embodiments of the present disclosure, the main functions of the radio frequency unit and the baseband processing unit include, but are not limited to: control and processing of wireless channels, transmission and reception of wireless channel data, modulation and demodulation of baseband signals on a wireless carrier, and transmission and reception of wireless carriers.
In the embodiment of the present disclosure, the main functions of the control operation and maintenance unit include, but are not limited to: the management of the state of each unit module, the configuration management of each unit module and the monitoring management of each unit module.
In the embodiment of the disclosure, the radio frequency unit may amplify, convert, mix, etc. signals received by the broadband antenna; the radio frequency unit can perform power amplification, antenna matching and the like during transmission; the radio frequency unit can process the received analog signals and then interact the analog signals with the baseband processing unit.
In the embodiment of the disclosure, the baseband processing unit can process the conversion between the analog signal and the digital signal, and modulate and demodulate the analog signal; the baseband processing unit may send the demodulated digital signal to the control and maintenance operation unit, or modulate the digital signal of the control and maintenance operation unit.
