How to simulate impulsive noise?

[sgr]

we usually use gaussian ditribution to model noise in communication systems,
anyone has any idea to simulate impulsive noise?

Re: impulsive noise

You can modelate it with a Poisson's process. This process have an input with this form:

z(t)=∑δ(t-ti)

because the process is activeds by a secuence of impulses ocurring at random times ti.

You need the set of Poisson points ti, with average λi and a real function h(t), then you have that the process is:

w(t)=∑h(t-ti).

If you use Campbell's theorem, the mean is η=λ∫h(t)dt and variance σ²=λ∫h²(t), where the limits of the integral are from -∞ to +∞
