Buffer in Simulink - Avoiding Latency Problem

Hi everybody I have a simple problem. I have a source block of frames [6x1]. After that I have an LDPC decoding block which receives blocks of size 64800x1 and with a coderate 1/2 outputs frames 32400x1. So I have to use a buffer of size 64800 before the coding block. The buffer inizializes to all zeros, so in the output of the buffer I have first 64800 zeros and then the real data. Is there a way to drop this bits before the decoding?

Hi!

Have fixed your problem? Because I believe that I have the same problem as you. I you have already fixed, can you tell me how?
