Abstract

The invention discloses a code automatic identification method and a storage medium, and the method comprises the following steps: carrying out the binarization of a signal probability vector threshold value: carrying out the binarization of a probability vector of a neural network into a 0, 1 vector according to the size of the threshold value; synthesizing a point bar signal: generating a pointbar signal vector according to the length of which the continuous two-dimensional value is 1; automatically grouping the point lever signal vectors by adopting a dynamic programming algorithm to obtain a point lever signal vector group; and encoding the point bar signal vector group according to the encoding table. By adopting the steps, the optimal grouping result can be well generated under various factors such as different rates, different habits of a sender and the like by adopting a dynamic programming algorithm, namely a DP algorithm. Compared with the traditional method of directly grouping according to the interval length, the method has stronger stability and adaptability. Automatic coding of the Morse telegram code in actual use is realized.

Description

technical field [0001] The invention belongs to the automatic identification technology of electronic codes, and in particular relates to an automatic identification method and a storage medium of electronic codes. Background technique [0002] Due to its high noise and channel instability, radio Morse code sound signals are manually recognized by professionals who have undergone long-term training throughout the country. The basic workflow is to listen to the sound signal, and at the same time translate it into numbers in real time according to the message type (long code, short code, word code, etc.), and record it. [0003] Manual identification has limitations such as high work intensity and insufficient professionals. [0004] Products with automatic recognition and coding in the prior art only exist in the simulator used for training, and the on-off signal is obtained and coded through the physically connected equal-amplitude transmitter (press the circuit to turn it ...
