[Discuss-gnuradio] use a file as source to the ofdm receiver

[bin zan]

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/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,
Bin
