The invention provides a method for transmitting an image signal based on the compressed sensing technology in a multi-hop wireless network. The method includes the steps that (1) original signals are packaged into a plurality of description packages with the equivalent information amount and the same significance through an encoder in a compressed sensing mode; (2) transmission benefits of each transmission link are calculated; (3) link connection needing to be built is determined according to the transmission benefits of the transmission links; (4) the transmission links are built according to the scheduling scheme, and transmission of the description packages is started. According to the method, encoding, decoding and route scheduling in image signal transmission are comprehensively considered, the high implementability is achieved, the method can be widely applied to existing wireless network transmission, the network transmission capacity is further improved, and the image signal transmission instantaneity and the image signal transmission effect are effectively improved.
Description
Technical field [0001] The present invention relates to a method in the field of wireless communication technology, in particular to an algorithm for image data encoding and packaging and data packet routing scheduling for the purpose of network output optimization, and specifically to a multi-hop wireless network based on compressed sensing technology The method of transmitting image signals. Background technique [0002] With the development of wireless network technology and the popularization of mobile devices, people's demand for mobile data services is increasing. Therefore, big data and real-time mobile data transmission have attracted more and more attention. This topic has not only been extensively studied academically, but also its application in industrial applications. Effective use of existing resources to provide users with mobile data services with better real-time performance and larger capacity is an important issue to be solved urgently. [0003] On the one han...
