Digital Signal Processing Based On Spline Functions

摘要

The development of the modern world's information and communication technologies and their implementation in various industries are important, are essential to the creation of parallel algorithms for solving problems of the recovery and digital signal processing, on the basis of the treatment processes a multi-core architecture and the search for optimal solutions. The current stages of development of the structure of machines, complexes and systems installed at facilities that are part of the structure of devices specialized for conducting scientific research or located on rolling stock are characterized by on-line analysis of complex processes and fields and increased demands on the speed of processing large amounts of data in real time. Particular attention is paid to the development of methods for solving problems of image and signal processing by using modern methods, algorithms and structural tools, architecture of computing and software. In that work the result of the study of methods of approximation of functions and functional dependencies obtained in the course of experiments for the selected class of signals improved method of spline functions on the basis of analytical analysis, parallel algorithms for digital signal processing have been developed, efficient algorithms have been developed for digital processing of vibrio signals in multi-core processors based on cubic and bi cubic basis splines.
