In subject area: Computer Science Additive White Gaussian Noise refers to the mixture of noises, including thermal noise and flicker noise, that is widely modeled as a Gaussian distribution with zero mean and v
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 transmission of information through non-ideal channel involves addition of additive white Gaussian Noise (AWGN) which plays significant role in distorting the information. REAL VERSUS COMPLEX GAUSSIAN DISTRIBUTIONS FOR DIGITAL COMMUNICATION If [DELTA][a.sub.n] = [[[DELTA]u(n), [DELTA]u(n -...
Digital pulse-position modulation (PPM) is a time-domain version of frequency-shift keying that encodes each variable pulse to a particular position within a period. Although numerous essays have researched PPM applied to optical fiber, the PPM process with additive white Gaussian noise (AWGN) was...
An upper bound on the error probability is obtained for digital communication (with average power Po and no bandwidth constraint) in the presence of additive white gaussian noise (with one-sided spectral density No) with the use of a noiseless feedback link. A repeat-request strategy is used:...
