Слайд 2

w(t) is added White Gaussian Noise
x(t) = s(t) + n(t),
n(t) =

nI(t) cos(2πfct) + nQ(t) sin(2πfct)
n(t) = r(t) cos[2πfct + ψ(t)], where

v(t) = signal term + noise term

Слайд 5

n(t) cos(2πfct) = {nI(t) cos(2πfct) + nQ(t) sin(2πfct)} cos(2πfct)
nI(t) =

2 n(t) cos(2πfct) & nQ(t) = 2 n(t) sin(2πfct)
