Here is an example where this method has been implemented.
We were trying to calculate the spectrum of a transmitted signal(Random signal/weighted pulse)
- The auto correlation function of the pulse which is not WSS because it is dependent on t:
- We associated a random variable(which is the delay) with an uniform PDF with the signal:
- PDF of the delay/the variable is:
I was unable to grasp the concept behind it, probably my basics are a bit rusty.
- By simply just associating a random variable (with an uniform PDF), how can we just make any random process a wide sense stationary process?
- Whats the concept behind it?
