Analysis of the noise and its influence on communication systems
Abstract
The paper aims at providing the communications engineer with guidelines in view to minimize the loss of information through signal reception and processing, by keeping to a minimum the introduction of noise at the different stages of data treatment. It summarizes, from this point of view, the many theoretical works found in the literature, and emphasizes the practical steps leading to the results. Noise and signal are considered through their respective spectral representations. This permits, through well known concepts, a definition of the effect of signal masking by the noise, and the calculation of the noise level as a function of processing means. Formulas established this way are easily applicable to various practical cases. Problems raised by the discovery of the signal within the noise are also mentioned.-
