Hello,

I am trying to create a simulation iwhere I will have a wireless signal that goes from one wireless node to another. I would like to be able to see waveform, as well as set up parameters, such as tx noise, ambient noise, message length, bitrate, etc. Is there any way to do it in Matlab? I've searched around but the closest solution to it that I found was here zigbee_spectrum_analyzer, however when I try to run the following command

model = 'simrfV2_zigbee_xtrans';
open_system(model);
sim(model);

it throws the error

No system or file called 'simrfV2_zigbee_xtrans' found.

and it looks like I have all tollboxes needed to run this script, which are

Signal Processing ToolBox

Communications Toolbox

and Communication Toolbox Library for the Zigbee Protocol

Also, my matlab version is R2018b. Please share any ideas or suggestions or code examples. Thanks a lot.

That example requires DSP System Toolbox, and the RF Blockset .

I don't know why the RF Blockset is a seperate product instead of part of one of the others, but so it is.

Hi, I did not know it either. So seems like with downloading RF Blockset Add-on the code runs fine on my machine. Thanks a lot, that solved my question.
