I values I got for sigma & A are extremely small, and the resulting cdf does
not addup to -80dBm.

This is what I did:

r_median = 1.177 sigma = 10^-7   (= -70dBm)
K = A^2 / 2 sigma^2 = 10         (= 10dB)

I have to multiply both sigma & A by 10^9 before computing p(r),
and multiply 10^-9 when plotting p(r).  Otherwise, the p(r) is too small.

The cumsum( p(r) ) does NOT hit 10^-8.  The max it hits is only
10^-9.  Is this approach correct?  BTW, will there be any TA office hours
for this course?

Regards,
Maria
