Description

Technical Field

[0001] The present invention relates to the field of wireless communication technology, and in particular to a lightweight scattering communication-in-motion device. Background Art

[0002] Tropospheric scatter communication is a beyond-line-of-sight communication method that utilizes the forward scattering of radio waves by scatterers in the tropospheric atmosphere. It is capable of resisting detection, interception, and interference, and boasts advantages such as high communication capacity and all-day usability. Scatter communication technology continues to evolve, with the application of various scattering schemes such as spatial diversity, time diversity, and frequency diversity. It has gradually evolved from the old small-capacity, dual-antenna scheme to the new large-capacity, single-antenna waveform. Technologies such as adaptive transmission and frequency hopping are gradually being applied in scatter communication, significantly expanding scatter communication capabilities and laying the foundation for scatter communication in motion. Faced with the growing demand for communication in motion, current scatter communication equipment is primarily used on the ground, and lightweight scatter communication in motion devices are still unavailable. The application scenarios of communication in motion dictate that the equipment must be lightweight to facilitate its installation on moving vehicles and ships.

[0003] The lightweight scattering CSM device acquires real-time positioning and directional information through the CSM antenna unit. Once the communication link is established, it tracks the communication direction in real time and can adapt to changes in the variable parameter channel, achieving rate and power adaptation, enabling the device to meet the requirements of CSM scenarios. The device module is integrated into the device housing, achieving lightweight equipment, meeting the requirements of CSM. Summary of the Invention

[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] A lightweight scattering communication-in-motion device includes a processing unit 1, a power amplifier unit 2, a radio frequency front-end unit 3, a communication-in-motion antenna unit 4, a power supply unit 5, and a device cover unit 6.

[0027] At the transmitting end, the processing unit 1 processes the sending data business, performs modulation, DA conversion, and up-conversion, and converts it into a radio frequency signal and sends it to the power amplifier unit 2. At the same time, the management data is processed and sent to the power amplifier unit 2, the radio frequency front-end unit 3, and the mobile antenna unit 4 for control interaction; the power amplifier unit 2 amplifies the scattered radio frequency signal according to the control signal and sends it to the radio frequency front-end unit 3; the radio frequency front-end unit 3 selects the duplex filtering channel and then transmits it through the mobile antenna unit 4.

After the processing unit 1 performs down-conversion, AD conversion, demodulation and other operations on the signal, it recovers the service information and other information transmitted by the channel.

[0029] The function of the processing unit 1 is to process baseband information, perform modulation and demodulation, and convert RF signals, so as to centrally realize intelligent strategies and management interactions. The sent service information and business information, etc., are sent to the modulation and demodulation 12 for baseband modulation and converted into an intermediate frequency signal after the business processing 11. The intermediate frequency signal then enters the agile frequency converter 13, is converted into the required RF signal, and is sent to the power amplifier unit 2. The received RF signal from the RF front-end unit 3 enters the agile frequency converter 13 of the processing unit 1 to complete down-conversion, and is converted into an intermediate frequency signal.
