3.2.2 White noise Gaussian noise is defined by its PDF, but white noise is based on the noise power. From the view of the spectrum, white noise power is a constant value. In an image with white noise, the intensity value of each pixel is different from its neighboring values. Figure ...
An example of zero-mean white Gaussian noise with a variance of σn2 = 0.25 is shown in Figure 3.3(b). Even if this assumption may not hold in certain cases, it does help make the mathematical analysis of digital communication systems tractable. The receiver has to make a decision on ...
The performance of specific signal constellations in digital communications problems is often described through use of the union bound, an upper bound which is asymptotically tight with respect to the signal-to-noise ratio. It is not unnatural to ask how tight this result is for small to medium...

We develop a simple analytic expression for the change in coherent weighted integration gain due to a white Gaussian error or noise in the phase of the integrated samples. Our expression is shown by simulation to be very accurate for any reasonable value of phase noise standard deviation. The ...
The whitened matched filter (WMF) is the optimum receiver filter for pulse amplitude modulation (PAM) and quadrature amplitude modulation (QAM) transmissions in the presence of intersymbol interference (ISI) and additive white Gaussian noise (AWGN). A new realization of the WMF is proposed, which...
By selecting a channel with a low noise floor ratio, the signal-to-noise ratio and the air interface rate can be increased. 3.4.2 Wi-Fi Transmission Latency There may be multiple Wi-Fi devices on the air interface. Therefore, Wi-Fi devices cannot directly send data but need to compete...
