Re: [Discuss-gnuradio] OFDM channel Estimation Block

You can of course add that later on, but don't forget to change both your include/blockname.h, your lib/blockname_impl.h and your lib/blockname_impl.cc. If you want to work with GRC, remember to edit the .xml in grc/, too!

Best regards,
Marcus

PS: gr_modtool doesn't do anything magical; it really just adds files with the content you specify. I'd like to encourage you to try around a bit more! You can't break much. And with version control (git) having your back, you can hardly do any harm even to your own work :)

Hii

One more doubt...
As the gr-digital / include/ ofdm_chest_vcvc.h file  have the argument list given as
      static sptr make(
      const std::vector<gr_complex> &sync_symbol1,
      const std::vector<gr_complex> &sync_symbol2,
      int n_data_symbols,
      int eq_noise_red_len=0,
      int max_carr_offset=-1,
      bool force_one_sync_symbol=false
      );

Do we need to give Argument list at time of gr_modtool add when it asks... Or we can add it later if we are not sure at the time of adding new block.

Hi Monika,

absolutely the same method:

cd gr-exisitingmodule
gr_modtool add

Note that this can only work with modules that follow gr_modtool's conventions (i.e. practically only with modules generated with gr_modtool in the first place)

Best regards,
Marcus

Hii

I understood how to create new module and block within this new module using gr-modtool from http://gnuradio.org/redmine/projects/gnuradio/wiki/OutOfTreeModules.

I want to add new block in the existing module. How can i do that ?
