I have question regarding Rician fading simulation. I am trying to develop Rician fading channel simulator in LabVIEW, but I ran into some problems. I have complex sinusoid as my line-of-signs signal. Then I generated white gaussian noise samples for I and Q components which represent one scatered wave. I added this scattered wave to my LoS sinusoid. According to this I should get a faded signal with folowing amplitude distribution at different signal amplitudes:
When I calculate amplitude and its distribution with histogram I get following result:
I am using the same amplitude values and sigma value. There is significant difference in these results and my questions are:
- What could be the problem here?
- If I make multiple scatered waves, will it make difference?
- Do I need to take into account Rician factor and somehow scale power of generated scatered waves?
