Abstract
The invention relates to a method for decreasing the frame error rate of information to be transmitted in the form of data frames in a data transmission system, in which the information to be transmitted is divided into data frames. The data frame is supplemented with error correction data generated by using part of the information to be transferred. At least part of the information to be used in the generation of error correction data is protected by error correction coding, by which an error correction coded data frame is obtained, in which different parts of the protected information have different error rates (BER). The error correction coded data frames are transferred in the data transmission channel from the transmitter to the receiver. The error rates of at least one part of the protected information are levelled out by shaping at the transmission stage that information part which is protected by error correction coding and which is used in the generation of the error correction data.
