Have any of you done anything like QPSK Modulation in python? I am in the middle of it and having problems in setting up bits? like odd and even bits.

Have you got any idea?

Regards,

Sam

    $\begingroup$ I didn't quite understand when you say "setting up bits" ?? $\endgroup$ – Saira Jun 7 at 17:56

    $\begingroup$ Welcome here! You forgot to ask a precise question. You've forgot to state what exactly you're doing, what the actual result is, and how that differs from what you expect. It's hard to help you. $\endgroup$ – Marcus Müller Jun 7 at 19:59
  • $\begingroup$ hey sorry guys, for asking unnecessary question i thought i didn't ask this. I figured it out later by using numpy and append function, i was stucked on iteration of array but now its ok. Thanks a lot. $\endgroup$ – Sam Jun 8 at 23:27

Are you using scipy by any chance ?

If yes , this might help

https://scikit-dsp-comm.readthedocs.io/en/latest/_modules/sk_dsp_comm/digitalcom.html

check for functions "QPSK_tx" and "QPSK_bb"

  • $\begingroup$ Thanks Sara! I was using the komm library, are you familiar with that to know how this compares? $\endgroup$ – Dan Boschen Jun 7 at 19:54
  • $\begingroup$ @DanBoschen . Nope. I haven't used komm library and was using scipy and MATLAB for DSP Comms. $\endgroup$ – Saira Jun 8 at 2:20
  • $\begingroup$ I appreciate the reference and look forward to comparing them. At first glance from GitHub stats: Scikit-dsp-comm: 6 releases since June 15, 2017, 5 contributors, 89 stars, last commit Dec 8, 2019, and komm: 17 releases since May 14, 2018, 2 contributors, 23 stars and last commit 13 days ago). $\endgroup$ – Dan Boschen Jun 8 at 2:30
