@Raj: Replies:
1/ Thanks.
2/ No, nothing on Coordinated Multipoint
3/ Digital Communication: Third Edition, by John R. Barry, Edward A. Lee, David G. Messerschmitt is a good reference
4/ Well, guess both are same. Agree?

Hi Krishna, how should i simulate SINR for cooperative MIMO scheme(considering interference from other cells).The SINR equation is given below SINR = ( |h11 |2 + |h12|2 ) E{x12} / σ2 + ∑ k=312 |h1k|2 E {xi2} my input is in terms of packets. please help me.

Hey,
Thank you so much for the wonderful work. It helped me a lot to start using Matlab for my work in wireless communications.
Do you have any article written on Coordinated Multipoint or Base Station Cooperation? Can you also give me a good reference to better understand MRC?
I have another question about your post. You have mentioned in the post that
“Given that we are equalizing the channel with h^H ”
Where h^H means the Hermitian transpose. But we are equlizing the channel with h+. Which is the pseusdo inverse of h. Aren’t we??

Hi Mr. Khrisna, can you show me why there is a negative sign in front of
-Eb_N0_dB(ii) in this code y = h.*sD + 10^(-Eb_N0_dB(ii)/20)*n;
Thanks so much.
