Thanks for reply,
Because in this site, http://gnuradio.org/doc/doxygen/page_ofdm.html
The figure in transmitting part,
http://gnuradio.org/doc/doxygen/ofdm_tx_core.png
"Virtual source" block shows "pre-ofdm", which means I need to create some
blocks like "Virtual sink" labeled "pre-ofdm" before this?
if yes, I am thinking to create the blocks like
"Random Source -> OFDM Mod -> Virtual sink"
I am not sure if
"OFDM carrier allocator, FFT, and OFDM cyclic prefixer" are doing the
same thing with "OFDM Mod"
Or should I change the
"OFDM Mod" block into like "PSK Mod"?
And about the error,
You were saying
"I think you just need brackets around the carrier allocation table.
Also, use Python's range() to make stuff more readable."
Can you explain it more specifically?
bracket at which section?
"python's range()" I have no idea what this is?
Thanks
