ABSTRACT:
The invention relates to a method of recovering lost bits in digital transmission. The invention can be applied in ATM networks or networks in which the receiver utilizes soft decoding. A number of data bits dl-dn are transmitted together with a number of control bits cl-ck. The control bits are calculated in the transmitter using a number of parity constants pll-pkn such that a corresponding number of parity relations are fulfilled. In the receiver, the positions of the lost data bits are detected and a number of syndrome bits sl-sk are calculated from the transmitted data bits and control bits. Then the lost data bits can be recovered by mapping syndrome bits indicating the values of the lost data bits. By using the knowledge about the positions of the lost data bits a reduced number of control bits are required compared with the prior art.
