Abstract:
A method for processing data to be transmitted via a channel, the channel having a specifiable variable data rate, the method comprising the steps of:a) dividing the data into predetermined bit classes, each of the predetermined bit classes corresponding to a respective error sensitivity;b) weighting the predetermined bit classes using weighting factors, wherein each of the weighting factors is determined as a function of an average error sensitivity of a respective bit class of the predetermined bit classes;c) providing predetermined error redundancy data to the predetermined bit classes, wherein at least one bit class of the predetermined bit classes which has a highest number of error-sensitive bits is provided with a higher error redundancy data of the predetermined error redundancy data; andd) assigning a code rate to a respective bit class of the predetermined bit classes as a function of a corresponding weighting factor of the respective bit class.
