The present invention relates to a telecommunication system comprising: an encoder for encoding input data; and a puncher (POIN) for punching the data according to at least two protection levels after encoding. The puncher comprises a basic structure comprising a first punching matrix (Pi), the output of which is fed to a demultiplexer (Mi) having a first output and a second output, the second output of which is fed to a second punching matrix (Pi + 1), in order to define at least two different protection levels obtained with a first output (Si) of the demultiplexer and an output (Si + 1) of the second punctured matrix, respectively. 本发明涉及一种电信系统，其包括：编码器，该编码器用于对输入数据进行编码；以及打孔器(POIN)，该打孔器用于在编码后根据至少两个保护级别对该数据进行打孔。该打孔器包括基本结构，该基本结构包括第一打孔矩阵(Pi)，该第一打孔矩阵的输出馈送到具有第一输出和第二输出的解复用器(Mi)，该第二输出馈送到第二打孔矩阵(Pi+1)，以便定义分别利用该解复用器的第一输出(Si)和该第二打孔矩阵的输出(Si+1)获得的至少两个不同保护级别。
