In this article, the analysis and evaluation of bit error probabilities of coherent MPSK nonlinear satellite communication systems were presented, in which there is uplink noise, downlink noise, and CW tone interference with random phase uniformly distributed over the interval [0, 2π].Abstract:
This paper presents the analysis and evaluation of bit error probabilities of coherent MPSK nonlinear satellite communication systems, in which there is uplink noise, downlink noise, and CW tone interference with random phase uniformly distributed over the interval [0, 2π]. The evaluation of bit probabilities also includes intersymbol interference whose statistical distribution is constructed through a two-dimensional moment technique. This moment technique is as effective and accurate as the standard Gauss quadrature formulas (GQF), yet more versatile than GQF for evaluating an expectation over random variables. Some numerical examples for the performance of satellite channels are illustrated.read more

TL;DR: The optimum repeater non-linearity is investigated and is shown to be a limiter at such signal-to-noise ratios and the error probability is found to be smaller than that of a linear system for all practical values of limiter and receiver input signal- to- noise ratios.

TL;DR: A novel quadrature model of the satellite nonlinearity is introduced, and is found to yield an excellent fit to the actual traveling wave tube characteristics as commonly used in a satellite transponder, with the advantage of requiring the choosing of only a few parameter values.
