Hello Experts: I know in the PLTS2013£¬have AFR(Automatic Fixture Removal) £¬it is better than TRL. But, I want to do it in ADS or Matlab environment, is it impossible? I read some paper, but I can¡¯t find the theory of AFR. The most important thing is split the S-parament to half. I think it need to covert freq domin to time domin,and cut off , then covert time domin to freq domin. This way can split the S-parament to half? Is it right? Who can help me?
