Hi,
If i know the direction of secondary users(in cognitive radio), how can i utilize this information in removing them and maintaining clean radio environment.Do i have to do mimo beamforming??

 

Hello,

Did you look for any information?
Here is a query from a search engine:

yup...i have looked for it extensively...most of them discuss about various methods of spectrum sensing and application of cognitive radio...they don't discuss about removal of secondary users.
