Hallo I am new,
my problem is simple but I have not found a solution:..
I spoke with a lot of professors of my University, but without results.
the problem is:
suppose you have the follow process:
A+x+i*y where A is a real positive constant while x and y are gaussian
random variates with null mean and variance sigma , therefore x and y are
indipendents.
i is sqrt(-1) .
if you compute the abs(A+x+i*y) you have for this new variabile a statistic
named Rice statistic, now what is the mean and the variance of this
statistic????
if I compute angle(A+x+i*y) what is the statistic of this variabile???
This is a problem most common in radar theory but the only solutions I have
found are for A=0 in which case abs(x+i*y) is a rayleigh statistic while
angle(x+i*y) is uniformly distribuited between -pi and pi.
Thank in advance
