Since the mean of noise is zero E[XY]=E[X]E[Y]=0 if X and Y are independent and E[Y]=0 It means that noise and signal are independent. Since the mean of noise is zero
E[XY]=E[X]E[Y]=0
if X and Y are independent and E[Y]=0

Thanks Nad Hi,
Can someone explain this claim (Note 1 above)
“The product of the signal and noise accumulated over many symbols average to zero”.
Thanks
Nad

If you sampling rate is constant, but has a bigger spreading code, then the data rate reduce. Agree? @Arif: Well, this depends on your simulation model.
