The present invention relates to the field of communication technology, and provides an encoding method, decoding method, encoding device, decoding device, storage medium and terminal. The encoding method includes preprocessing a random binary sequence, and adding a symbol 0 after each symbol 1 ;Initialize the binary sequence to be encoded so that the probability value of the encoding starting point and the probability distribution interval are 1; calculate the corresponding encoding probability in sequence according to the symbol order of the binary sequence, wherein, if the current symbol is symbol 1, the symbol of the encoding probability needs to be calculated is symbol 1 and symbol 0, and the corresponding encoding probability is superimposed. If the current symbol is symbol 0, the symbol that needs to calculate the encoding probability is symbol 0, and the corresponding encoding probability is superimposed until the end of the binary sequence One symbol, the encoding is complete. The entire encoding process can achieve the minimum data transmission error at the minimum time cost.
Description
technical field [0001] The present invention relates to the technical field of communication, and in particular provides an encoding method, a decoding method, an encoding device, a decoding device, a storage medium and a terminal. Background technique [0002] Digital signal transmission refers to the method of transmitting a message with a digital signal payload. The universal process is the change process of the probability of the symbol in the time series, and the probability of the symbol in the random process is not subject to external interference in the time series, which is the standard model. The standard model is an ideal model. If the probability of the symbol is disturbed by the outside in time series, there are three basic situations: standard, so that the probability does not change; contraction, so that the probability becomes smaller; expansion, so that the probability becomes larger. Specifically, the universal process theory is as follows: a random sequen...
