Performance analysis of the SS-CSC System using synchronizing spreading code
Proceedings of ISSSTA'95 International Symposium on Spread Spectrum Techniques and Applications, 1996Co-Authors: T. Takebayashi, H. Habuchi, T. HasegawaAbstract:In this paper, the performance of the spread spectrum communication constrained spreading code (SS-CSC) System using synchronizing spreading code is discussed. In particular, the bit error rate (BER) and the initial acquisition time are evaluated by theoretical analysis. Moreover, the performance of this System is compared with that of bi-Orthogonal System. Consequently, it is found that the average acquisition time increases and the BER decreases when increasing E/sub info//E/sub sync/. Moreover, the SS-CSC System with the canceller is superior about 5.5[dB] to the System without the canceller when the BER is 10/sup -6/ and E/sub info//E/sub sync/ is 0.5. The SS-CSC System using a synchronizing spreading code had better use the canceller in order to reduce E/sub info//E/sub sync/. The BER of the SS-CSC System using the synchronizing code is the same as that of the bi-Orthogonal System.

On the SS-CSC System with a synchronizing spreading code
Proceedings of IEEE 3rd International Symposium on Spread Spectrum Techniques and Applications (ISSSTA'94), 1994Co-Authors: H. Habuchi, T. HasegawaAbstract:M-ary spread spectrum communication (M-ary/SS) Systems have been growing in interest because their bit error rate performance can approach Shannon's limit. However, M-ary/SS Systems have two serious problems, namely a complexity of the System and an instability of synchronization. The authors reported the spread spectrum communication constrained spreading code (SS-CSC) System which has a simple structure. In the paper, the SS-CSC System with a synchronizing spreading code is proposed. In particular, bit error rate (BER) properties of the proposed System are evaluated. Consequently, it is found that a canceller is useful to reduce the cross-correlation value between each spreading code for information and the synchronizing spreading code. Moreover, the BER performance of the proposed System with the canceller is better than that of the M-ary/SS System with a canceller under conditions of the same frame length. The BER performance of the proposed System is much the same as that of the bi-Orthogonal System.

On the series expansion approach to the identification of Hammerstein Systems
IEEE Transactions on Automatic Control, 1991Co-Authors: M. PawlakAbstract:A polynomial identification algorithm for recovering a nonlinearity in the Hammerstein System is proposed. The estimate employs the Legendre Orthogonal System with adaptively selected number of terms. The global consistency along with rates of convergence are established. No assumptions concerning continuity of the nonlinearity or its functional form are made. A data-driven method using the cross-validation technique for selecting the number of terms in the estimate is presented.

Single-Phase Power Theory Using Orthogonal Transformations
Advances in Electrical and Electronic Engineering, 2011Co-Authors: Branislav Dobrucký, Marek Roch, Wael HosnyAbstract:The paper deals with the new method of power analysis of single-phase power electronic Systems. Using a new particular transform theory the ordinary single-phase System can be transformed into equivalent two-axis Orthogonal one. The new original thought is based on the idea that ordinary single-phase quantily can be complemented by fictious second phase so that both of them will create Orthogonal System, as it usual in three-phase Systems. Application of the above theory makes this possible to use complex methods of analysis as instantaneous reactive power method, which have not been usable for single-phase Systems so far. All types of the power, active and reactive, can be determined by this way.

Instantaneous single-phase System power demonstration using virtual two phase theory
2008 International School on Nonsinusoidal Currents and Compensation, 2008Co-Authors: Branislav Dobrucký, Michal Pokorny, Mariana BenovaAbstract:The paper deals with the virtual approach and application of Orthogonal transform theory, used for ordinary single-phase System to its transformation into equivalent two-axes System. It is well known that the analysis of multiphase Systems can be more simple using the Park/Clarke transform into two-axis stationary (alpha, beta) or rotary (d, q) reference frame. The above transform can be used for electrical machines as well as for power electronic Systems. The projection of time state-space vector for any quantity of symmetrical three-phase System in Gauss complex plane (alpha + jbeta) shows out six-side symmetry of vector quantity trajectory. Then, analysis of such System can be focused on the interval equal to 1/6 of the time period only. It is clear that when using similar transform of single-phase quantity into equivalent two-axes Orthogonal System it will be possible to use all advantages as in three-phase transformed System with respect of 4-side symmetry instead of 6-side of previous case. Analysis in such Orthogonal coordinates System will then be identical to the three-phase one under Park/Clarke transform, including determination of instantaneous reactive power. The presented method creates a virtual two-phase System from the original singlephase System by adding a new fictitious phase. The new thought is based on the idea that ordinary singlephase quantity can be complemented by virtual fictitious phase so that both of them will together create Orthogonal System, as is usual in three-phase Systems. Application of above-mentioned theory makes it possible to use complex methods of analysis as instantaneous reactive power method. Both, the active and reactive powers can be determined by this way. Practical application of the method is outlined for the case of active and reactive power determination for single-phase power active filter, unified power flow controller, and dynamic voltage restorer, Fig.1 [14], [15], [17] - [19].

Proceedings of the Power Conversion Conference-Osaka 2002 (Cat. No.02TH8579), 2002Co-Authors: Branislav Dobrucký, V. Racek, Marek Roch, Michal PokornyAbstract:The paper deals with the new method of analysis, synthesis and experimentation of single-phase power active filters.

Application of above theory makes possible to use complex methods of analysis as instantaneous reactive power method, which have not been usable for single-phase Systems so far. Both, the active and reactive powers can be determined by this way. Practical application of the method is outlined for the case of reference current determination for single-phase power active filter. The paper shows some examples of the simulation verification results, which proved a high accuracy and extremely fast response of the single-phase active filter with control, based on the introduced method. The effectiveness of proposed control algorithm is also demonstrated by experimental results, which were carried out on the single-phase active parallel filter.
