Abstract

The invention relates to an encoding error correction method of power line power frequency communication. The method comprises the following steps: receiving a R (x) code, calculating a syndrome S (x) according to the received R (x) code, calculating an error position polynomial sigma (x) according to the syndrome S (x), solving a root of the polynomial sigma (x) to acquire an error position number, calculating an error pattern E (x) according to the error position number, and calculating a C (x) code with errors corrected through the R (x) code and the error pattern E (x). By adoption of the encoding error correction method provided by the invention, random errors and burst errors can be corrected, the encoding error correction efficiency is effectively improved, and the accuracy of the power line power frequency communication is effectively improved.

Description

technical field [0001] The invention relates to the technical field of power line power frequency communication, in particular to a coding error correction method for power line power frequency communication. Background technique [0002] Power line power frequency communication uses small distortions of grid voltage and current waveforms to carry information to achieve two-way communication. Since low-frequency distortion signals can be directly transmitted across transformer stations, this technology is expected to play an important role in distribution automation and other fields; at the same time, because power lines are not Special communication lines, the complex structure of the distribution network and the interference noise generated by various power loads will cause errors in power frequency communication data. In order to improve communication performance in a strong noise environment, error correction coding is a technical means that must be adopted . [0003] E...
