Simulation code for “Rayleigh Fading Modeling and Channel Hardening for Reconfigurable Intelligent Surfaces, IEEE Wireless Communications Letters, to appear.
Thank you very much for sharing the code for the reproducible research, I have a question about the paper ''Rayleigh Fading Modeling and Channel Hardening for Reconfigurable Intelligent Surfaces''.
In equation (2), the PDF function has the term cos(\theta), which implies that there is a greater probability when \theta value is close to 0 than \pi/2. In my opinion, it contradicts with isotropic distribution.
I look forward to your answers to my misunderstanding.
