I am new to communication simulation. I have a project which needs to calculate SINR. SINR = P/(N+I), and here the noise is white Gaussian noise. Generally speaking, is there any reference value of standard deviation of white Gaussian noise?

What is the definition of standard deviation?Standard Deviation is a statistical tool that is used widely by statisticians, economists, financial investors, mathematicians, and government officials. It allows these experts to see how variable a collection of data is. Furthermore, SD is calculated as...
The standard deviation σ and the variance of a random variable are related by the formula σ=Variance. Equivalently, Variance=σ2.There is a formula expressing the variance in terms of the expected values of X and X2 that is used in many statistical...
Standard Deviation is determined by measuring the square root of the average squared differences among data points and the overall population mean. The formula is as follows: Where: 1) Xi = Value of ith point in dataset 2) x̄ = Mean value of the dataset 3) n = Number of data points...
