Hi,
I need to simulate Phase Noise effect on the Sine wave at frequency offset from 100 HZ to 10e6Hz away from the original frequency with power levels associated with it.
I tried to use comm.phasenoise block and is giving error.
clc;
clear all;
close all;
Fs = 5e09; % Setting up Sample Rate
f = 1000e06; % Setting up the Frequency wants to generate
n = 1:1:4800; % Setting up Memory Points
x = sin(2*pi*(f/Fs)*n);
y = cos(2*pi*(f/Fs)*n);
Combine = complex(x, y);
abc = Combine';
hPhNoise = comm.PhaseNoise('Level',[-67 -75 -96 -96 -97 ], ...
'FrequencyOffset',[100 1e3 10e3 100e3 1e6 ], ...
'SampleRate',Fs);
STEP = step(hPhNoise, abc);
Thanks,

Hi,
Your code is run without any errors for me. Kindly post the error you encountered while executing the code. You may also use the following code instead of step() to add the noise to the signal.
Out=hPhNoise(inputColumnVector);
