Universal mobile telecommunications system (UMTS) is one of the 3rd generation (3G) cell phone technologies. The capacity of UMTS is interference limited. Radio resources management (RRM) functions are therefore used. They are responsible for supplyi

Comparison of Fuzzy Logic and Genetic Algorithm Based Admission Control Strategies for UMTS System

Autor: Kejik, Petr, Hanus, Stanislav

Publikováno v: Radioengineering, Vol 19, Iss 1, Pp 6-10 (2010)
Radioengineering. 2010, vol. 19, č. 1, s. 6-10. ISSN 1210-2512

CDMA systems have so-called soft capacity, so the total number of possible sessions has not an exact value. The capacity of CDMA system depends on the interference level in the system. There are therefore RRM (Radio Resources Management) functions, w

Co-channel and Adjacent Channel Interference Measurement of UMTS and GSM/EDGE Systems in 900 MHz Radio Band

Autor: Gleissner, Filip, Hanus, Stanislav

Publikováno v: Radioengineering, Vol 17, Iss 3, Pp 74-80 (2008)
Radioengineering. 2008, vol. 17, č. 3, s. 74-80. ISSN 1210-2512

This paper is concerned with inter-system and intra-system interference measurements of 2.5G and 3G mobile communication systems. The both systems UMTS and GSM/EDGE are assumed to operate in a common radio band of 900 MHz. The main system parameters

UMTS Network Model for Interference Analysis - Optimization of Spreading Codes Order

Autor: Ruzicka, Zdenek, Hanus, Stanislav

Publikováno v: Radioengineering, Vol 16, Iss 3, Pp 72-76 (2007)
Radioengineering. 2007, vol. 16, č. 3, s. 72-76. ISSN 1210-2512

This article deals with mathematical modeling of UMTS network. The presented model is designed for interference analysis in this network. The paper presents the set of simulations based on an idea of a specific order of Walsh codes. In the first part

Optimized Second-Order Dynamical Systems and Their RLC Circuit Models with PWL Controlled Sources

Autor: Pospisil, Jiri, Kolka, Zdenek, Hanus, Stanislav, Petrzela, Jiri, Brzobohaty, Jaromir

Publikováno v: Radioengineering, Vol 13, Iss 3, Pp 13-17 (2004)
Radioengineering. 2004, vol. 13, č. 3, s. 13-17. ISSN 1210-2512

Complementary active RLC circuit models with a voltage-controlled voltage source (VCVS) and a current-controlled current source (CCCS) for the second-order autonomous dynamical system realization are proposed. The main advantage of these equivalent c

Optimized State Model of Piecewise-Linear Dynamical Systems

Autor: Pospisil, Jiri, Kolka, Zdenek, Hanus, Stanislav, Michalek, Vaclav, Brzobohaty, Jaromir

Publikováno v: Radioengineering, Vol 12, Iss 1, Pp 27-29 (2003)
Radioengineering. 2003, vol. 12, č. 1, s. 27-29. ISSN 1210-2512

The conditions for an optimized design of the second dynamical system having low eigenvalue sensitivities are directly derived. Their more general form is in accordance with the previous results obtained by using linear topological conjugacy.
