Hello, According to the website, http://gnuradio.org/doc/doxygen/page_ofdm.html I would like to realize the transmit part. However, when I tried to execute it, there is error on " ofdm_carrier_allocator<http://gnuradio.org/doc/doxygen/classgr_1_1digital_1_1ofdm__carrier__allocator__cvc.html> "

Should I generate the "random source", make "ofdm Mod", and create the" virtual sink called pre-ofdm"? Thanks Kevin
