摘要

The method involves obtaining a polynomial if a Grobner base contains only 1 component. A derivative of the polynomial is calculated, a large common divisor of the derivative and the polynomial is calculated and another polynomial is calculated based on previous polynomial and the divisor, if the base contains 2 components. Values tagging erroneous aggregates of a received word are obtained by calculating roots of the latter polynomial. Independent claims are also included for the following: (A) a coded digital signal reception apparatus comprising a decoder with a device for locating erroneous aggregates of components of a received word (B) a removable data storage unit having instructions for executing steps of an erroneous aggregates locating method (C) a computer program comprising instructions permitting a data processing device to implement erroneous aggregates locating method.
