noise vs interference

[fuzzyrabo]

hi,

does any one have a good documentation explain the difference between noise interference. or has a good explation for both i would really he thankfull.
thanks.

What i know is that "interference", after it is processed by the receiver along with the desired signal is called "Noise"..

In another definition, Noise is defined as interference from Machines or Natural/Physical sources..
Interference is usually termed as unwanted signal directly being generated by known/unknown transmitter on the specific frequency on which the local receiver is tuned.

from wikipedia [Interference (communication)]
"Interference is typically but not always distinguished from noise, for example white thermal noise."
http://en.wikipedia.org/wiki/Interfe...communication)

Johnson–Nyquist noise - Wikipedia, the free encyclopedia

Noise is usualy thermal noise, calculated by formula
FkTB and is -174dBm at 18 degrees celsius at 1Hz bandwidth.

GOOD EXPLANATION..

the difference between them is very clear , the main difference between them is the causes:
exampl:
Noise : caused by : Hight temperature (thermic noise),Noise ;
the noise's effect is always decreasing the Rx level.
interference : caused by : frequencies that are closes to each other.
the interference's effect may increasing the Rx level, but broke the link (communication).
they're many differences and that's what i have in my head.
