Gaussian Noise Generator (GNG) IP Core ================================================== Introduction ---------------------------------------- The Gaussian Noise Generator core generates white Gaussian noise of standard normal distribution, which can be used to measure BER to extremely low BER levels (~10-15). The core uses a 64-bit combined Tausworthe generator and an approximation of the inverse normal cumulative distribution function, which obtains a PDF that is Gaussian to up to 9.1¦Ò.
