We can do Equal gain combining, Selection Diversity, and Maximal Ratio Combining (MRC). The MRC is optimal.

How to do equalisation if you are working on same program using rayleigh channel.

thank you

So i need your help. thank you sir... i am waiting for your reply hello sir,

In WirelessCafe, you (and your team) have posted nice contents. I have bookmarked for future read. Keep up the good work. Hopefully, we can figure out of some ways to network and reach a wider audience in future. @Ashwini: Thanks for the link.
