**BPSK BER in rayleigh IN MATLAB : why noise and channel are the same in matlab.**

I have a look on people's matlab on BPSK BER over rayleigh channel.

I don't understand why noise and channel are the same as shown below. so rayleigh channel is the same as noise then?

Can anyone explain it to me please.

noise=1/sqrt(2)*(randn(1,N)+1i*randn(1,N)); %AWGN noise with mean=0 var=1

h=1/sqrt(2)*(randn(1,N)+1i*randn(1,N)); %Rayleigh Flat Fading - single tap
