  • Convolutional/Single Parity Check Turbo Codes for Wireless Multimedia Communications 

    Kostov, N. (Společnost pro radioelektronické inženýrství, 2004-12)
    Error correction codes are widely used in digital communications to improve the Quality of Service. The Quality of Service is typically expressed in terms of maximum acceptable frame error rate and bit error rate. The key ...
  • Mobile Radio Channels Modeling in MATLAB 

    Kostov, N. (Společnost pro radioelektronické inženýrství, 2003-12)
    In this paper, a MATLAB based approach for mobile radio channels modeling is presented. Specifically, the paper introduces the basic concepts for modeling flat fading channels in MATLAB by means of user-defined m-files. ...
  • Motion Detection Using Adaptive Temporal Averaging Method 

    Nikolov, B.; Kostov, N. (Společnost pro radioelektronické inženýrství, 2014-06)
    Motion detection methods are widely integrated in modern intelligent video surveillance systems. Many of these methods use background subtraction techniques to separate the foreground objects from the background. Temporal ...
  • Power Parameters and Efficiency of Class B Audio Amplifiers in Real-World Scenario 

    Zhivomirov, H.; Kostov, N. (Společnost pro radioelektronické inženýrství, 2017-04)
    Consumer audio amplifiers are intended to op¬erate with various loudspeaker loads, i.e. the load imped¬ance profile of the audio amplifier is a priori unknown. We propose the power parameters analysis of the class B audio ...
