Hi I'm doing a report on noise in communication systems and I can't find enough info anyone that can help????
Also I'm doing a reaserch on simulating noise in computers ???

So thats it

All the Best Gentleman

Greetings Gentlemen:

Here are a couple specific resources for you. Noise in communications systems has got to be one of the most widely written-about topics, so your delimma will be more one of sorting through the plethora of information out there, not finding it in the first place.

National Instruments Communications Tutorial Series ... D4007962D4

Online Resources for Understanding Noise and its Measurement ... _Noise.pdf

Noise & Interference (EMC mitigation)

Simulation of Communications Systems ... mmtuto.pdf

What about simulating AWGN in computers does anyone know where I can get this type of info. I know is based on Gaussian statistics but HOW?????????????????????????????/ :?:

I would think the dominant noise in a computer is the multiple clocks, their harmonics, and their mixing products - very nasty. It is the reason that building WLAN and Bluetooth into computers has been so difficult. So AWGN probably pales in comparison. In other words, the dominant noise in a computer chassis is not white noise (random) at all, but highly predictable.

This might be of use. Also, search on the NIST website for specifically what you're looking for. Our tax dollars have funded a lot ofresearch on the topic.
