noisecu

Analytic complex uniform white noise

Calling Sequence

NOISE = noisecu(N)

Parameters

N:

a positive integer: the length of the noise signal.

NOISE:

a complex column vector of size N: the noise signal.

Description

noisecu computes an analytic complex white uniform noise of length N with mean 0.0 and variance 1.0.

Examples

N = 512; noise = noisecu(N);
m = mean(noise)
sigma2 = sum((noise-m).^2)
subplot(211); plot(real(noise)); a=gca(); a.data_bounds = ([1 N -1.5 1.5]);
f = linspace(-0.5,0.5,N);
subplot(212); plot(f,abs(fftshift(fft(noise))).^2);
