Polynomial Toolbox
Hromčík, M. ; Šebek, M. ; Ježek, Jan
Quite recently the polynomial design methods found a new great field of application outside the control area: the algebraic approach have been used successfully in signal processing and mobile communications. In contrast to the control systems synthesis, polynomials and polynomial matrices with complex coefficients are often required when designing filters, equalizers, decouplers and other components of mobile phones for instance.

Implementation of Sliding Mode Control in SIMULINK 4.1 (R12.1)
Belda, Květoslav
The paper briefly introduces Sliding Mode Control (SMC) of the planar redundant parallel robot. This type of the robots seems to be one of the promising ways to solve the problems of accuracy and speed. The main goal is presentation of using MATLAB-SIMULINK environment verion 4.1 (R12.1) for simulation of such control of the robot. Implementation is accomplished by combination of S-Function and ordinary Function, both programmed in C code as mex Functions.

Utilization of Matlab for the logarithmic processor development
Líčko, Miroslav ; Matoušek, Rudolf ; Pohl, Zdeněk
Microprocessors are using the floating-point units for the real data type manipulation. Basic research has indicated, that the logaritmic number system can offer new possibilities of implementation for the algorithms, especially for algorithms widely using multiplication, division and square root operations. In this article there's a short summary of the development, evavaluation and demonstration with the utilization of Matlab.

Tuning and implementation of DSP algorithms on FPGA
Líčko, Miroslav ; Pohl, Zdeněk ; Matoušek, Rudolf ; Heřmánek, Antonín
The article describes an algoritms development process for FPGA. It is shown on the example of the implementation of the QR RLS algorithm. To realise it means to perform operations such multiplication, division and square root.The research indicates, that the logarithmic arithemtic unit can reused for the real data type processing in some cases such a QR RLS algoritm.The developed prototype of logaritmic unit is tested on DSP algorithms using Matlab.
