1)How to generate h(128 by 1 matrix),channel impulse response for a rayleigh fading channel(speed-120km/hr)..relative delays[0 781 1563 2344],avg power[0 -3 -6 -9]..max doppler shift 150 HZ,carrier freq-1 GHZ

2)How to approximate channel impulse response(h(t)) using linear prediction model: h(t)=n+yt,where n and y are zero-order and first order parameters of the model..?Matlab program?where h(t)=(n11,y11,n12,y12,...,n89,y89)
