fNo: AWGN

Description

Generates a vector of normally distributed noise samples with mean of zero and noise spectral density (No/2), a.k.a. AWGN.

Usage

fNo(N, No, type = "real")

Arguments

N

- number of noise samples

No

- noise spectral density

type

- "real" or "complex" defaults to real

Value

returns a vector of distributed noise samples of length N, mean of zero and variance of No/2
