Problems with file sink block in grc

GNU Radio
1

Dear all,

I have tested the file souce and file sink in grc:
file source-- throttle— file sink
The source file is a mp3 file withe the size 3.615.346 bytes
The sink file is smaller (unbuffered off): 3.612.672 bytes
The sink file (unbuffered on ) is also smaller 3.615.344 bytes.
The files should have the same size.
I would like to set up the ofdm transmission system and compute the bit
error rate for example that would not be possible.
Can somebody help me?
Thanks!

Have you tried removing the throttle block? That could be backing it
up such that the source finishes and shuts down the flowgraph before
the last block of data is processed. For this type of application, you
probably don’t need a throttle, anyways.
