Hi all! I am a rookie and I am working about OOK mod and demod. I have few questions following:
I modify the digital_constellation.cc file as d_constellation[0]=gr_complex(0,0) d_constellation[0]=gr_complex(1,0) like this, I think after re-make, I already achieve OOK mod. However, in order to build ook demod, I modify as following: return (real(*sample)>0.5) I also embed OOK mod and demod into GRC and try to simulation in GRC whose flow graph is File Source->packet Encoder->OOk mod->Channel Model->Throttle->OOk demod->Packet decoder->File sink. If there is no noise in channel model, ook mod and demod work perfect, but if there is any noise, I can not receive any file. Anyone can tell me if I did wrong in modifying the code or there are still something I need to modify. Thank you for time and help very much!
