Hi @hao02.wang,

Welcome to the Aerial forum!

Please review section “5G Model for testing and validation” of cuPHY developer guide. Let us know if you have any further questions.

Thank you.

Dear @bkecicioglu,

Thanks for your reply.
Here is our purpose : we found RKHS based SRS channel estimator in the source code, and we want to do the test for its performance, but failed. What we did is modify the yaml file and run “runSim” function. Is there any method or test case could we do this? or further more, is there any reference paper or material for this algorithm?

Thank you.

Hi @hao02.wang,

We are sorry for the delayed response.

You can find a high level overview of the RKHS algorithm here. We unfortunately do not have a detailed documentation for the RKHS implementation.

If you set the following flag in Matlab, you can enable RKHS.

SimCtrl.alg.ChEst_alg_selector = 2; % flag indicating PUSCH channel estimation algorithm to be used in 5GModel and cuPHY-CP. 0: MMSE; 1: MMSE_w_delay_and_spread_est . 2: RKHS ChEst

Thank you.
