	IR UWB modulation methods Bezucha, Petr This essay deals with ultrawideband signals and analyses possibilities of their impulse generation and their code and data modulation. Detailed record
	Software radio in the mobile radio-communication /telephony/ Ďurovič, Svetozár In the paper various applications of software radio in wideband mobile telephony systems are presented. The architecture of the basic parts of the mobile systems 3G is described and special attention to the technical problems is given. The report contains many computer programs to illustrate the mathematical procedures. Detailed record
	Multiuser detection Šimša, Jan In the invited lecture the principles of multiuser detectors for code division digital signal transmission and their approximations by suboptimum detectors were explained. Detailed record
	Principles of spread spectrum systems-CDMA Šimša, Jan The contribution summarizes principles of spread-spectrum communication systems. These principles are utilized in code-division multiple-access systems of a simultaneous utilization of the same communication channel by multiple users. Detailed record
	Analysis of influence of code doppler on mean acquisition time in direct sequence spread spectrum communication systems with serial search Bezucha, Petr ; Hovorka, Ladislav This contribution shows influence of code Doppler on mean acquisition time of a serial search direct-sequence spread/spectrum pseudo/noise code acquisition system in Gaussian channel. Results of this analysis enable us to set the parameters of this system to the optimum values and minimize the mean acquisition time. Detailed record
	Code division multiple access Šimša, Jan Detailed record
	Convergence of mixed and mobiles telecommunication services Ďurovič, Svetozár Detailed record
	Mean acquisition time of serial spread spectrum PN acquisition system in the presence of carrier doppler Bezucha, Petr Detailed record
	Dispersion of random code acquisition time of direct sequence spread spectrum receiver Šimša, Jan Detailed record
	The transmission of digital television with the spectrum spread system Ďurovič, Svetozár Detailed record
