[Octave-patch-tracker] [patch #9019] communications package: alternative qammod, bin2gray, recpulse, rcosfir

[anonymous]

Follow-up Comment #2, patch #9019 (project octave):

Hello, 

I'm sorry but I do not know how patch against the communications repository
:(. The only way I've seen is explained here but I'm not sure about doing it
well. 

http://octave.sourceforge.net/developers.html
  
If you don't mind I'll just explain the changes here. 

1) qammod (updated) - now it is able to modulate the x sequence with gray
coding (for square constellations) and with user defined coding. Before it
only used binary coding, i.e. not coding.  

2) bin2gray - convert binary to gray code for square constellations. 

3) rectpulse - repeats n times each IQ sample

4) rcosfir - implements cosine and root cosine filter

5) upfirdn - Discard it, the current implementation is far better. 

Regards,
