Patent ID: 8792375

Claim:
A data rate matching method for use in a data rate matching apparatus including a plurality of interleavers in mobile communication systems, comprising: calculating a set of first parameters (f 1 ) based on a length (D) of encoded input data input to the plurality of interleavers in series or parallel; calculating a set of second parameters (f 2 ) based on a set of prime numbers constituting a value of the length (D) of the input data; and performing interleaving based on the set of first parameters (f 1 ), the set of second parameters (f 2 ), and the length (D) of the input data, wherein the performing of the interleaving includes generating interleaved output data by applying the first parameter (f 1 ) and the second parameter (f 2 ) to Π(k)=mod((f 1 k+f 2 k 2 ), D), where k=0, 1, . . . , K Π and K Π denotes a size of a matrix.
