摘要：This paper deals with the using of adaptive filtering in the area of telecommunication technology. The study focuses on the possibilities of design and implementation of adaptive filters based on virtual instrumentation in the LabVIEW development environment from the American company National Instruments. The selected adaptive algorithms (LMS, NLMS, RLS, QR-RLS) are implemented both in LabVIEW and C# programming language in the form of dynamically linked DLL (Dynamic-Link Library) libraries. The experiments test the reliability and speed of the implemented algorithms using them for the suppression of the echo in sound signal. Based on the findings from the implementation, a comparison of both options is made by evaluation of the computation time and improvement of signal-to-noise ratio (SNR).
