Design and simulation of the serial concatenated and parallel concatenated schemes for forward error correction

Abstract

: Design of the error correction systems based on sequential concatenated convolutional codes and turbo-like codes, including the design of decoding schemes for these codes, are considered in the paper. The complexity of the implementation of the considered forward error correction methods is discussed. Based on simulation modeling, the performance of the serial concatenated and parallel concatenated coding schemes are obtained as the dependence of BER (bit error rate) on the noise level for Gaussian channel. Abstract: The computational (numerical) diameter is used to completely solve the problem of approximate differentiation of a function given inexact information in the form of an arbitrary finite set of trigonometric Fourier coefficients.
