Abstract： |
The present invention belongs to the field of communication technology. Said method incldues: on the basis of cyclic characteristics of RS code it effectively utilizes RS code to receive relationship of before polynomical cyclic shift and after polynomical cyclic shift and correlation of error position of long burst, and the error position of long burst error is assumed to be lowest 2t bit for receiving polynomical, so that it can simplify the interpretation method into the method of that firstly making cyclic shift of received polynomical, then resolving error image by using a group of linear equation. Said invention uses relative small decoding time-delay and relative high information transmission rate to implement decoding error correction suitable for long burst error. |
