Thanks for your feedback, really appreciated.
1- Does that also applied to the antenna separation with WINNER2 channel model, similar to the demo in reproduciblity model ?
2- And is the horizontal separation between antenna port produce NO grating lobes in both winner and 3D model?
3- Finally, could you please let me know if there is a limit to the antenna separation (upper bound), what factors control this separation ?, and weather if there is an optimum maximum separation so that the data throughput is maximized ?
Thanks for your help.
