    Models for SoC Infrastructure of Radio Frequency Identification with Code-Division Multiple
    (EWDTS, 2012) Filippenko, I. V.; Hahanova, I. V.; Filippenko, I. O.; Maksimov, M.; Chugurov, I. N.
    Application of the direct spread spectrum technology to radio frequency identification system for solving problems of speed, reliability and electromagnetic compatibility is considered. The models of systems-on-chips for tag and reader of RFID systems with code-division multiple, based on technology of direct spread spectrum, are proposed. Nowadays, the most promising technology for automatic identification is radio frequency identification (RFID), when data is transferred without any mechanical contact between the devices. Contactless identification technologies correspond to all the requirements of computer control systems, where recognition and registration of objects are realized in real time. Modern infrastructure of RFID systems (Fig. 1) involves readers, tags and various protocols, which allow integrating the system in global information networks and variety of applications of enterprise levels. In addition, the infrastructure can also include other devices, such as bar code readers, input/output devices, for instance label printers, motion detectors, photo sensors. Transponder and reader communicate with each other by using radio frequency channel. Wireless data channel is the most vulnerable link in the system, because the data transmitted by radio channel, may be intercepted. Also the problem of electromagnetic compatibility of various wireless devices is important. This paper is devoted to solving this problem through the creation of models of systems-on-chips for tag and reader by using the direct spread spectrum technology (CDMA).

    Verification and testing RKHS series summation method for modelling radio electronic devices
    (EWDTW, 2005) Chumachenko, S. V.; Chugurov, I. N.; Chugurova, V. V.
    Reproducing Kernel Hilbert Space (RKHS) for Series Summation that allows analytically obtaining alternative representations for series in the finite form is developed. To increase efficiency of solving of computational tasks there are used mathematical co-processors, which implement most efficient ways of computing equations, integrals, differential coefficients, ets. It is obvious that after discovering of new methods of increasing computation accuracy and decreasing computation time it is necessary to re-implement mathematical coprocessors or use new generation of IP-cores in PLD, Gate Array, ASIC designs. The method of reduction of computation of certain types of series to exact function that is widely used during calculation of parameters of high radio frequency devices was presented in [1-4]. This method decrease computation time of such tasks in tens and hundred times and its inaccuracy is equals to zero. The purpose of the investigation is verification and testing Series Summation Method in RKHS for modelling radio electronic devices.
