Hi,

I have been trying to figure this out for two days but I don't seem to be reaching a conclusion

Let me describe what I'm doing...

I have a vector of constants:

I obtain a vector of random values, by adding a vector of AGWN, , to :

Finally, I compute between and :

As you can see, the value of would change each time I generate a new vector of AWGN noise. Therefore I will average over several trials.

What I can't get my head round ishow can I decide how many trials are enough?

I have gone on various errands to standard error of the mean, confidence intervals, and Monte Carlo trials, without fruition.

Your input is appreciated!

Thanks.
