METHOD FOR SYNDROME DECODING FOR CONVOLUTION CODES Russian patent published in 2006 - IPC H03M13/23 

FIELD: radio engineering, possible use in radio communication systems for correcting multiply repeated errors in communication channel.

SUBSTANCE: in accordance to method, non systematic convolution encoder is utilized with modulus two adders, number of which determines speed of code, while adders are represented by generative polynomials, which determine communication types between register cells, and during decoding, in accordance to method, principle of syndrome decoding of block codes is utilized for guaranteed correction of multiply repeated errors, also to end of input informational series, number of zero symbols is added by one lesser than number of memory cells, in decoder, syndrome calculation is performed and correction of errors, while building of vector of errors is performed on basis of comparison of received syndrome with standard syndromes.

EFFECT: simplified method of generation of code combination, and simplification of device for guaranteed correction of multiply repeated errors.
