Abstract:
1. A method for data rate matching, the method comprising the steps of: distributing data to be transmitted as bits over a set of frames via a first interleaver; carrying out a repetition method, for purposes of the data rate matching, on the transmitted data after interleaving such that a same number of bits are repeated in each of the frames, and the repeated bits have as uniform as possible a spacing from one another with regard to a sequence of the transmitted bits upstream of the first interleaver; and applying, in displaced fashion, a repetition pattern of the repetition method, which is applied inside a first frame of the frames, and also inside further frames of the set of frames, wherein a repetition rate is not an integral fraction, and wherein a displacement S(k) of the repetition pattern to the set of frames is performed using a displacement of a next lower repetition rate that is an integral fraction, wherein the displacement S(k) of the repetition pattern to a frame k of the frames is obtained via: calculation of a mean repetition distance q, using the following formulation: calculation of the S(k), the displacement of the repetition pattern each column k, using the following formulation: end for, and displacing the repetition pattern of the frame k by the amount S(k).
