adding white noise on a received signal
adding white noise on a received signal
(OP)
hello
I have created a pulse signal (transmitted and received), and I want to add a white noise with a variance of 1 to the received signal, but I don't know how to do this. if someone can help me?
thanks

RE: adding white noise on a received signal
Create a 2^n long array for the modulus, and shape this to the desired profile against frequency
Create an array for phase, and fill it with random numbers between 0 and 2 pi
Do an IFFT of this data, to give a real time series. This is a time history of statistically valid Gaussian white noise.
