I am trying to simulate 16 Qam system on a flat fading rayleigh 2x2 mimo broadcast channel with zero forcing precoder..
So the model is:
y=Hx+n:
but instead of sendin X i m sending H inverse multiplied with x
i guess dis is d essence of d zf precoding
so finally d data recieved at d reciever is just x+n;
so d channel behaves like d normal awgn channel..
but zf precoding is still considered not a good tool to use..why?
hod do i show dis wid simlation
