The invention relates to a method for recovery of lost and/or corrupted data which are transmitted from a transmitter device (10) to a receiver device (12). First, coding of said data is performed by means of an encoder (14) connected to the transmitter device (10). Subsequently, said data is transmitted from the transmitter device (10) to the receiver device (12) via a transmission system (18), and said data is decoded through application of a Low Density Parity Check method by means of a decoder (16) connected to the receiver device (12), wherein lost and/or corrupted data is restored during decoding. According to the invention, in a first decoding step, an iterative decoder (16a) is used. In a second decoding step, a maximum-likelihood decoder (16b) is used, said second decoding step is performed if said data cannot be sufficiently recovered by the iterative decoder (16a). The maximum-likelihood-decoder complexity can be limited by the adoption of an abortion parameter. |
