Noise in Communication Systems - RF Cafe Forums

RF Cafe Forums closed its virtual doors in 2010 mainly due to other social media platforms dominating public commenting venues. RF Cafe Forums began sometime around August of 2003 and was quite well-attended for many years. By 2010, Facebook and Twitter were overwhelmingly dominating online personal interaction, and RF Cafe Forums activity dropped off precipitously. Regardless, there are still lots of great posts in the archive that ware worth looking at. Below are the old forum threads, including responses to the original posts.

NOTICE: The original RF Cafe Forum is available again for reading, and the new RF Cafe Blog is an active board.

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

Online Resources for Understanding Noise and its Measurement

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.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
