Hi,

I was trying to understand the MATLAB 5G toolbox. However, I did not see any DAC block in any given example of link level simulation or testing example given in MATLAB 5G documentation. For example,

Am I missing something? Any suggetion would help.

Hello @Md. Hasan Rahman,

I can understand you are looking for a Digital-to-Analog Converter (DAC) block to model the behavior of DAC in simulations. However, in the 5G Toolbox, the focus is primarily on modeling and simulating the physical layer of 5G wireless communication systems, which includes various aspects such as channel modeling, waveform generation, modulation, coding, and link-level simulations. The 5G Toolboxdoes not provide a specific DAC block as part of its built-in blocks or examples.

However, if you want to incorporate a DAC model into your simulation, you can create a MATLAB function to model the behaviour of a DAC. The following documentation provides further information on this: https://in.mathworks.com/help/releases/R2021b/matlab/ref/function.html.

Thanks,

Asim
