Use a file as source to the ofdm receiver

GNU Radio

Hi,
I am using ./usrp_rx_cfile.py collecting ofdm signals into a file.
Then
I use it as import into a ofdm receiver {self.u =
gr.file_source(gr.sizeof_gr_complex, “data.dat”, False)…}
, the method followed by the website "
http://www.mail-archive.com/[email protected]/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,

Hi,
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,
Bin
