Problems solved by technology
However, in wireless electromagnetic wave communication in a complex medium environment, due to the influence of environmental factors such as turbulence, sea waves, water, clouds, and fog, long series of burst errors occur
In this case, only relying on error control coding technology cannot correct a long series of burst errors, thus affecting the correct transmission of information

The invention discloses a Spinal code coding and decoding interleaving strategy and device based on a Q learning algorithm. A transmitting end of the Spinal code coding and decoding interleaving strategy structure comprises the steps of: determining a number W of transmitted coding symbols through using a Q learning strategy, generating W coding symbols by a Spinal code coding end, and carrying out interleaving of the W coding symbols through using a 3GPP standard interleaver, and finally, sending the W coding symbols to a transmission channel after modulation. A receiving end comprises the steps of: carrying out demodulation and de-interleaving by means of the 3GPP standard interleaver to obtain W coded symbols, decoding the W coded symbols one by one by means of the Spinal code decodingend, judging whether decoding is successful or not, if decoding is successful, entering transmission of a next information bit sequence, and if decoding is not successful, continuously sending the coded symbols according to the Q learning algorithm until the maximum transmission frequency is reached. The Spinal code coding and decoding interleaving strategy and the device are suitable for application scenarios of wireless electromagnetic wave communication systems such as free space optical communication, terahertz communication, millimeter wave communication, microwave communication, optical(electromagnetic) sound fusion communication and the like, and are used for guaranteeing the stability and reliability of communication.
Description
technical field [0001] The invention relates to the technical field of forward error control in wireless electromagnetic wave communication systems such as free space optical communication, terahertz communication, millimeter wave communication, microwave communication, optical (electromagnetic) acoustic fusion communication, etc., and specifically relates to a Spinal based on Q learning algorithm Coding and decoding interleaving strategies and devices. Background technique [0002] In complex wireless communication environments such as the atmosphere, underwater, and air-water cross-media, the transmitted modulated signal will be attenuated due to factors such as turbulence, scattering, absorption, and interference, which will cause the information beam to be interfered during transmission, seriously affect the communication quality. Therefore, it is necessary to adopt effective error control technology to ensure the stability and reliability of the wireless electromagneti...
