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]);
subplot(212); f=linspace(-0.5,0.5,N);
plot(f,abs(fftshift(fft(noise))).^2);
