SCCDMA functionality

[patel999jay]

Hello there,

Thanks for your wonderful work. This is not an issue, just a question, Is there SCCDMA functionality with this package ? I did lookup the multi-carrier modulation and scfdma examples, is there a example for multiple access technique such as dsss or cdma ?

Hello
Thanks for the feedback (and sorry for the delay of my answer).
For the moment, there is only functions and methods for the multicarrier waveforms and nothing on Spread Spectrum. I would definitively fall into the scope of DigitalComm.jl. If you have any PR, it would be very welcome.

Any idea of what you would need ?

Hi,

I am interested on how to perform some kind of multiplexing where there are more than one user transmitting on single channel at same time and we could save bandwidth with that. I would think of CDMA. I have an example of it. If we could speed that up with julia that would be wonderful.

What are your thoughts on this ?

Sounds good and interesting. I may have some time soon to provide a first base for kind of CDMA (maybe using OVSF codes?). In the meantime if you have any code to provide, I will be pleased to review PR ;)

I have pushed a first version of CDMA (with OVSF code, and spreading associated to code size) on the branch cdma if you want to have a look to #10

@RGerzaguet awesome. I will take a look and will contribute to that for sure. Thanks for the consideration.
