    problem with QAM simulation..plz help

    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

    Re: problem with QAM simulation..plz help

    Oh... overall i have to show that zf precoding is not a very good precoder as compared to the mmse or the sphere precoder..and compare there performances over a rayleigh fading channel..
    Can you help me with the simulation in some way?
