Hi All,

I saved gr_ofdm_mapper_bcv.* files as other name say
gr_new_ofdm_mapper_bcv.* in the same directry, because I need some
modification based on these later. After that, I did
/gnuradio/gnuradio-core/src/lib$ make
/gnuradio/gnuradio-core/src/lib$ sudo make install

I don't know whether I need make and make install to let
gr_new_ofdm_mapper_bcv.* work. Actually, I don't know how to get
gr_new_ofdm_mapper_bcv.* play their role. However, when I run
$sudo ./ -f 460M -T A --tx-amplitude 5000 -v -i 128
--fft-length 128 --occupied-tones 100 --cp-length 32

I got error
terminate called after throwing an instance of 'std::invalid_argument'
  what():  gr_ofdm_mapper_bcv: occupied carriers must be <= fft_length

Before any change here, works fine. Could anyone
me? Thanks so much!
