Abstract

The invention discloses an encoding method, a decoding method, an encoding device and a decoding device, which do not need to perform logical judgment operation on initial data to be encoded, only need to select a first quantity of bit data from the initial data to be encoded as encoding bit data, and encode the encoding bit data to obtain target data. Each piece of bit data in the initial data is encoded to obtain first data; and meanwhile, the target data is inserted into the first data to obtain second data after the initial data is coded. The whole coding method is simple, so that the whole coding design is relatively simple; and the decoding logic operation and the coding logic operation are the same, so that the design difficulty of the decoding circuit is reduced.

Description

technical field [0001] The present application relates to the field of data transmission, and in particular to an encoding method, a decoding method, an encoding device and a decoding device. Background technique [0002] When a digital signal is transmitted in a digital channel, it is necessary to encode the digital signal in the computer before baseband transmission. The purpose of encoding is to make the transmission signal a square wave with a certain jump, so as to avoid too many consecutive 0s or consecutive 1s, which will cause errors in the clock synchronization information received by the receiving end, and eventually lead to bit errors. At present, the most widely used encoding scheme in the field of data transmission is realized through a series of logical operations. The encoding method process is too cumbersome, which increases the amount of calculation and difficulty of implementation, and at the same time greatly increases the process and difficulty of decodin...
