Hi all:
Have you ever using the gnuradio/gr-digital/examples/ofdm/rx_ofdm.grc?And I change the rx_ofdm.py as follows:
self.connect((self.digital_ofdm_chanest_vcvc_0, 1), blocks.file_sink(gr.sizeof_gr_complex * fft_len, 'channel-estimate.dat'))
And i use the matlab:
csi=read_complex_binary('channel-estimate.dat');plot(1:64,real(csi(1:64,1)),'rs-')
The result is attached.But I think the result is wrong.Have someone do the similar thing like me?Can we discuss this?
Environement: 2 USRP N210 and SBX
Thank you.
Best regards,
