Use the classical MIMO equation, for a 4x4 MIMO system, channel matrix is defined as [3 1 1 1; 1 4 1 1; 1 1 5 1; 1 1 6 1], TX signals on each antenna for five time instances are, s1=[1 2 3 4 5] s2=[2 3 4 5 1] s3=[3 4 5 1 2] s4=[4 5 1 2 3] Assume noise is uniformly distributed random number in the interval (0,1) (rand(4,1) in matlab command, it generates noise for one time instance. note that the s1 through s4 have five columns which represent signals at five different time instances. You have to generate the noise matrix five times for five difference time instances.). Using Matlab, to calculate the received signal at each antenna for five time instances respectively.

If you code your command in a .m file, submit the m file please attach. If you use command line, use "diary" command to save your commands into the text file and attach to answer please.
