[Discuss-gnuradio] Adding a custom modulation

[连非儿]

Hi.

I am testing my custom modulation scheme ppm.py. I followed this post http://lists.gnu.org/archive/html/discuss-gnuradio/2010-12/msg00265.html

to register this modulation into mods/demods. I added a line

import ppm

in my benchmark_tx.py.

I also tried placing the ppm.py file in blks2impl directory. However neither method worked. The result from "print digital.modulation_utils.type_1_mods()" did not contain ppm.

Another issue is that I modified digital_constellation.cc, and I called functions in the modified digital_constellation.cc in my ppm.py. In this case should I rebuild gnuradio? If not, what should I do?

Any suggestions?

Thanks!
