In a device for determining a position of a bit error in a bit sequence, a check matrix is used which has a predefined number of rows and a predefined number of columns. The check matrix includes a plurality of square submatrices having a submatrix row number and a submatrix column number corresponding to the predefined number of rows or the predefined number of columns of the check matrix. The device for determining then includes a unit for receiving a bit sequence and a unit for identifying a syndrome using the check matrix and the received bit sequence. Furthermore, the device includes a unit for establishing a position of a bit error in the received bit sequence, wherein the unit for establishing is adapted to identify a syndrome bit and a syndrome bit group in the syndrome, and wherein the unit for establishing is further adapted to determine the position of the bit error in the received bit sequence using information on a position of the syndrome bit or the syndrome bit group in the syndrome, information on a relationship between the syndrome bit and the syndrome bit group, and a submatrix row number or a submatrix column number of a submatrix.
