Create a semi-random pulse train

Hi there!

I'm trying to simulate a real-life situation for a Smart Grid system. I need to recognize a given pulse train in a transmission line and differentiate it from random pulses that also come at any given time in the line.

The pulse train to be recognized is a simple 1:1 pulse train of say 5 pulses of same amplitude, 4 Ampere for example. I'm using the autocorrelation function to analyze the signal and see if the pulse trains distinctive triangle-shaped ACF is found.

My problem right now is in the simulation of the random pulses that also come in the line, something like the following:

I just want to see how the Autocorrelation Function of a signal like this would differ from a periodic pulse train using autocorr, which I've already done.

Any ideas on how to simulate the random pulses? I've tried with ones-zeros to create a random array but its not going how I want to...
