Problems solved by technology
[0003] Usually, ultra-wideband technology is realized through coherent receiving ultra-wideband systems. Due to the need for carrier recovery, channel estimation and system synchronization, the requirements for equipment and debugging are very high, and the construction cost is high.
[0004] With the rapid development of the mobile Internet, various communication systems coexist and communication standards emerge in endlessly, which poses difficulties for the compatibility of communication systems in various countries.
In order to adapt to different communication systems, it is obviously not feasible to build different ultra-wideband transceiver systems

Embodiment Construction
[0036] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0037] The present application discloses a transceiver system based on software radio. The transceiver system includes a sending end and a receiving end. The sending end includes a first terminal and a first communication software radio peripheral (USRP, Universal Software Radio Peripheral), and the receiving end includes a second terminal and a second communication software defined radio peripheral.
[0038] Wherein, the first terminal is used for the terminal to obtain the source video data, perform application layer channel coding on the source video data, integrate the channel coded signals into data packets at the network layer, and perform differential chaos keying on the data packets at the physical layer (DCSK, Differential Cha...

The disclosure relates to a software radio-based transceiver system and a video transmission method, belonging to the field of video transmission. The video transmission transceiver system in the embodiment of the present disclosure includes a sending end and a receiving end. The first terminal at the sending end is used to obtain source video data, perform application-layer channel coding on the source video data, and packetize the channel-coded signal at the network layer. Integration, the data packet is processed by differential chaotic keying modulation at the physical layer to obtain the transmission data packet, and the channel coding of the application layer adopts a code-free channel algorithm; the second terminal at the receiving end is used to perform differential chaotic keying demodulation on the transmission data packet The processing and decoding process recovers the source video data. The software-defined radio-based modulation transceiver system builds a hardware platform with wide applicability, which is beneficial to system upgrades.
Description
technical field [0001] The present disclosure relates to the field of video transmission, in particular to a software radio-based transceiver system and a video transmission method. Background technique [0002] At present, with the rapid development of 5G Internet of Things, in the face of the increasing demand of large-scale users for communication with each other, the network traffic of online video has experienced explosive growth. Ultra Wideband (UWB: Ultra Wideband) technology is an important technology for short-distance communication of the Internet of Things. It has the advantages of high transmission rate, low power consumption, resistance to multipath interference, simple implementation and high security. It is suitable for dense multipath environments and is It is one of the best schemes for indoor high-speed, short-distance access communication, with broad application prospects and important theoretical research value. [0003] Usually, ultra-wideband technolog...
