What is envelope correlation and why it is important to be low in MIMO applications?
it should be noticed that envelope correlation is: ρe = 〖| S11^* S(21 )+ S12^* S22 |〗^2
------------------------------------------------------------------------------
(|(1-〖|S11 |〗^2-〖|S21 |〗^2)(1-〖|S22 |〗^2-〖|S12 |〗^2)|)
it should be noticed that envelope correlation is: ρe = 〖| S11^* S(21 )+ S12^* S22 |〗^2
------------------------------------------------------------------------------
(|(1-〖|S11 |〗^2-〖|S21 |〗^2)(1-〖|S22 |〗^2-〖|S12 |〗^2)|)
Envelope correalation said relation between S parameters in MIMO array. It said independent between antennas so the value of this paramet should be very low.
