How can I create a MIMO block diagram to design MIMO system model? It would be more beneficial if MU-MIMO (Multi user multiple input multiple output) system model is available.
The procedure of building a MIMO block diagram is pretty similar to a SISO system's. The only difference is that you have to add more connections between different elements of the system. To this end, the information provided in the following can be very useful:

You can also easily create an "Embedded MATLAB Function" in MATLAB which can be in formed as MIMO.
Following document can also be useful:

Prof. B.B. Kathiriya had completed his dissertation in field of MIMO.You can get more information from him.
Dear Arjav,
There are functions available in Simulink in MATLAB as well as in LABVIEW.
Any latest Text book on Wireless Communications Provides the MIMO system Model
If your channel fading is Rayleigh, you can produce a M*N matrix (M is the number of users, N is the number of BSs) in which the matrix elements are Rayleigh random variables considering shadowing effect and multipath. Multipath and shadowing should be calculated for each / BS pair and inserted in the matrix. Then you can recall the users fading coefficient form the matrix. By this way your simulation speed increases.
