5G/NR - Pre Trial - Frame Structure - Matlab Code   

 

 

 

NOTE : This note is about a tempary 5G specification that was implemented and tried before 5G specification is finalized. I keep this note for study purpose.

 

Frame Structure - Matlab Code

 

Disclaimer : The code is ONLY for visualzing the resource element mapping for various physical channels defined in Pretrial specification. The resoure location would be accurate but the data assigned in the resource elements is just a dummy (meaningless) value. Also, there might be some errors in the code (or my mis-interpretation of the specification). Don't blame on me if there is any errors :). Play with the code and have fun.

 

 

Tips for Execution

    i) Create a folder where you want to store files (m files)

    ii) Create the files listed under Common Library Section store them in the folder created at step i).

    iii) Create other files as you like and store them in the folder created at step i).
