Transceiving system based on software radio and video transmission method

Abstract

The invention relates to a transceiving system based on software radio and a video transmission method, and belongs to the field of video transmission. The video transmission transceiving system comprises a sending end and a receiving end, and a first terminal of the sending end is used for obtaining source video data, performing application layer channel coding on the source video data, performing data packet integration on signals subjected to channel coding in a network layer, and performing differential chaotic keying modulation processing on data packets in a physical layer to obtain a transmission data packet, wherein the application layer channel coding adopts a code-rate-free channel algorithm; and a second terminal of the receiving end is used for carrying out differential chaotickeying demodulation processing and decoding processing on the transmission data packet to recover the source video data. According to the modulation transceiving system based on software radio, a hardware platform with wide applicability is constructed, and system upgrading and updating are facilitated.

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...

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
