[Discuss-gnuradio] could you give me tips for saving ofdm data? and interpolation?

[James Park]

Hi,

 

I was able to get the data using file_sink with benchmark_ofdm_tx.py 

 

self.file_sink = gr.file_sink(gr.sizeof_gr_complex, "filename.dat")
self.connect(sef.txpath, self.file_sink)

 

and could see frequency spectrum using fft and fftshift in matlab.

 

also, I extended receive_path.py with file_sink, but data did not look match with transmit data.

Could you give me tips for that?

 

if I want to calculate the exact real time, can I divide x value by 64M and interpolation value?

Thank you for your help.
