Article is devoted to use of redundancy of the correcting codes protecting the transmitted data from mistakes, for detection of borders of code combinations. Algebraic decoding with syndrome calculation is for this purpose used. Thus the syndrome at each subsequent shift of coming information on one category pays off not anew, and with use of value of the previous syndrome that will allow to accelerate calculation process considerably. Thus the clock frequency of operation of the device won't exceed the frequency of arrival of information from a communication channel.
