Encoding method, decoding method, related device and storage medium

Abstract

The embodiment of the invention discloses an encoding method, a decoding method, a related device and a storage medium. The encoding method comprises the following steps: acquiring a first bit streamof original encoded data; performing a preset logic operation according to the first bit stream to obtain a second bit stream, with the number of bits of the second bit stream being greater than the number of bits of the first bit stream; whether the logic values of the last two bits in the second bit stream are the same or not is judged, if so, subjecting the logic value of at least one of the last two bits to negation processing, and acquiring a third bit stream; and inverting the target bit in the third bit stream, and inserting the inverted target bit as a flag bit into the first bit of the third bit stream to obtain target coded data. According to the embodiment of the invention, the problem of no code in the channel transmission process of the information is solved, so that the signal transmission quality is improved.

Description

technical field [0001] The present invention relates to the field of encoding technology, in particular to an encoding method, a decoding method, a related device and a storage medium. Background technique [0002] Digital signal coding technology aims to convert binary 0 / 1 digital data into a square wave waveform with certain polarity, amplitude, bit rate, and jump rules. During the serial transmission of the signal, the transmitted data can be encoded into a code stream containing clock frequency components, so that the receiving end can extract clock synchronization information from the code stream, and the clock synchronization information can ensure that the receiving end follows the correct timing from The original data is reproduced from the received signal. However, when the signal has too many consecutive 0s or consecutive 1s during transmission, the receiving end is prone to phase shift or frequency deviation when the data is restored. This error is called called ...

Problems solved by technology

During the serial transmission of the signal, the transmitted data can be encoded into a code stream containing clock frequency components, so that the receiving end can extract clock synchronization information from the code stream, and the clock synchronization information can ensure that the receiving end follows the correct timing from The original data is reproduced from the received signal. However, when the signal has too many consecutive 0s or consecutive 1s during transmission, the receiving end is prone to phase shift or frequency deviation when the data is restored. This error is called bit error

[0003] In the existing data transmission technology, the signal is prone to bit errors during transmission. So far, there is no effective solution
