Embodiment Construction

[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0025] refer to Figure 1 to Figure 2 , the present invention is made up of link controller 1, modem 2, transceiver 3, power amplifier 4 and duplexer 5, figure 1 It is an electric principle block diagram of the present invention, and the embodiment is according to figure 1 Connect the lines.

[0026] The role of the link controller 1 is to group and encode the received external message data; organize the message packet data to be sent according to the received error information and send it to the modem 2; After the packet data is integrated into a complete data message, the complete data message is sent out according to the interface protocol.

[0027] The modem 2 completes the modulation of the burst frame, and outputs the modulated IF signal to the transceiver 3 ; demodulates the received IF modulated signal, and sends the demodulated dat...

Abstract

The invention discloses a full-duplex meteoric trail communication device based on a single antenna, and relates to the field of meteoric trail communication. The device comprises a link controller, a modem, a transceiver, a power amplifier, and a diplexer. The device employs the diplexer which is large in withstood power, is small in incoming loss, and is high in receiving and transmitting isolation. A receiving channel and a transmitting channel are combined into one full-duplex channel under the condition of guaranteeing the communication performance of a system. The full-duplex communication between different meteoric trail communication devices can be completed through one antenna, thereby reducing the number of antennas, reducing the requirements for an antenna construction field, and shortening the starting construction time of meteoric trail communication. The device is large in withstood power, is high in receiving and transmitting isolation, is simple and convenient in starting construction, is high in integration degree, is stable and reliable in performance, is especially suitable for a meteoric trail communication occasion where the antenna construction field is limited and there are special requirements for starting construction.

Description

technical field [0001] The invention relates to the field of meteor trail communication, in particular to a single-antenna-based full-duplex meteor trail communication device, and is especially suitable for full-duplex meteor trail communication occasions where the antenna erection site is limited or there is a time requirement for erection. Background technique [0002] The transmission loss of meteor trail communication is about 180dB, the transmission path is as long as 2000km, and the strength of most received signals is between -110dBm. Therefore, meteor trail communication requires a high system gain to ensure system performance. [0003] In full-duplex meteor trail communication, a high-power transmitter of several hundred to several kilowatts is usually used to increase the system gain, and at the same time, the out-of-band noise of the high-power transmitter is suppressed by about 120dB to avoid falling into the receiving channel The transmitter sideband noise inten...
