     Let me clear my issue. My source file includes number of complex numbers which can be read by using matlab function "read_complex_binary.m". I observed that the data are same as when they passing through "gr_file_source::work" ->???-> "gr_ofdm_frame_sink.cc" however, I observed that in "gr_ofdm_frame_sink.cc", the data are totally changed.  Does anyone what happened in between? 

Thank you,

, the method followed by the website "http://www.mail-archive.com/address@hidden/msg20498.html"

However, using matlab code "read_complex_binary.m" the complex number I got is different from what I print out from gr_ofdm_frame_sink::work. Can anybody help me?

Thank you,
