5g NR PBCH DMRS & SSS channel estimatiom

Hello, I'm studying 5G NR Synchronization Procedures.

I have a question how PBCH-DMRS and SSS perform channel estimation.

'NR Synchronization Procedures' example in 5g toolbox use 'nrChannelEstimate' function.

(https://www.mathworks.com/help/5g/examples/NR-Synchronization-Procedures.html)

And I also read documentation for 'nrChannelEstimate', but I don't understand how the function operates.

(https://www.mathworks.com/help/5g/ref/nrchannelestimate.html)

I want to know the paper that explain the algorithm of channel estimation for PBCH-DMRS and SSS.

Thanks.

Hi Chanuk,

You can use edit option in the MATLAB command window to know more about the functionality of 'nrChannelEstimate' function.

edit nrChannelEstimate

[Chanuk Jung]

I already read that.

But, I didn't understand how the function operates.

I want to know what channel estimation technique was used on function 'nrChannelEstimate'.

Thanks.
