In this process, one input row generate three rows of output as follows. Next step is Rate Matching step. This is the most mesterious part to me. The generic Idea is like this. bins a 1:5NettetDescription. out = lteRateMatchTurbo (in,outlen,rv) performs rate matching of input data in to create the output vector out with length outlen.
