GMSK modulator

hi,

Currently I'm working in my final year project. I need to design a GMSK modulator using MATLAB. Could anyone provide me any info?
Thank you.

Thank you.

GMSK modulation is simular to MSK modulation except a gaussian impulse is required.

Hope that helps.

Regards.

Re: GMSK modulator

What component should be used to produce Gaussian impulse? because I'm creating .mdl file for GMSK modulator.

You can use a lookup table to creat the Gausian impulse.

Re: GMSK modulator

Hello guys,

where can I find material and files on the analysis and design of Modulators using Matlab?

I'm just entering this topic.

Thanks in advance.

Re: GMSK modulator

Hi Lupin,
if you want to design modulator in Matlab, you need to create a model file. All the components can be find in library browser.


Hi Sixth,
I never use a lookup table before. Can you show me the way?


Thanks

Hi Lupin

I hope you have the communication toolbox with your matlab instalation, searh in the help section how to use it.

To Peichimlin

you can find the equation of Gaussian pulses in https://mathworld.wolfram.com/GaussianFunction.html
if there is not that function already in matlab. Then generate a table with vales for x an y.
