In communication systems, signals are often superimposed with noise during transmission, and Gaussian white noise is commonly used for analysis. This program generates Gaussian white noise with customizable parameters such as mean, variance, and signal length.

Detailed Documentation

In communication systems, signals transmitted through channels are frequently subjected to various interferences, with noise being the most common. Noise refers to unwanted components in signals that may originate from weather conditions, hardware imperfections, electromagnetic interference, or other factors. During signal analysis, noise processing is essential, and Gaussian white noise serves as a fundamental model for such scenarios. This program generates Gaussian white noise using mathematical algorithms, typically involving random number generation with normal distribution properties. The implementation may utilize functions like randn() in MATLAB or equivalent libraries in other languages to create noise sequences with zero mean and specified variance. By adjusting parameters, users can simulate real-world noise conditions to enhance signal analysis accuracy and system performance evaluation.
