Ljiljana D. Mili c and Miroslav D. Lutovac Abstract|The IIR realizations of the Hilbert transformer require less computations than FIR realizations, but the main disadvantage of the minimum phase IIR realization is the nonlinearity of the phase characteristic. In this paper, we show that using allpass IIR sub lters from the minimal phase solution it is possible to design an IIR Hilbert transfor...

This work concerns the optimal regulation of single-input-single-output nonminimum-phase nonlinear processes of relative order one. The problem of calculation of an ISE-optimal, statically equivalent, minimum-phase output for nonminimum-phase compensation is formulated using Hamilton-Jacobi theory and the normal form representation of the nonlinear system. A Newton-Kantorovich iteration is deve...

Linear approximations of nonlinear systems can be obtained by fitting a linear model to data from a nonlinear system, for example, using the prediction-error method. In many situations, the type of linear model and the model orders are selected after estimating several models and evaluating them using various validation techniques. Two commonly used validation methods for linear models are spec...

Controlled intersymbol interference may be used to design bandwidth efficient coded modulation schemes. The performance of the optimum receiver depends only on the free distance of the code and is independent of its phase. Large reductions in receiver complexity are obtained by using reduced search detection techniques like the MAlgorithm (MA). However, we show that MA detector performance depe...

Abstract: In this paper, we show that adaptive controllers designed using the standard backstepping technique proposed in Krstic [1995] globally stabilize a class of uncertain systems with unknown input time delay and unmodeled dynamics. As such systems belong to nonminimum phase systems and thus our result extends the class of systems stabilizable from minimum phase systems when the standard b...

In this paper, we propose a decoder for low-complexity equalization of coded frequency selective multiple-input multiple-output channels. The decoder combines the Parallel Decision Feedback Decoding (PDFD) and the List-type approach. This alternative achieves a good trade-off between performance and complexity even when the channel is not minimum phase.

We give an explicit parameterization of all causal stabilizing repetitive controllers for single-input/single-output continuous time non-minimum phase systems of a certain class. When the plant meets certain conditions, using the parallel compensation technique, we obtain the parameterization of all repetitive controllers. Finally, a numerical example shows the effectiveness of this parameteriz...

[1] This study uses TRMM lightning and radar observations to study the fundamental relationship between precipitation ice mass and lightning flash density. The results indicate that the physical assumptions of precipitation-based charging and mixed phase precipitation development are robust and that on a global scale, the relationship between precipitation ice water path and lightning flash den...

The problem of the non-causal inversion of linear multivariable discrete-time systems is analyzed in the geometric approach framework and is solved through the computation of convolution pro#les which guarantee perfect tracking under the assumption of in#nite-length preaction and postaction time intervals. It is shown how the shape of the convolution pro#les is related to both the relative degr...

This paper presents an override controller which ensures that constrained output variables retain certain prescribed strict bounds. The class of nominal closed loop systems considered for the constrained output regulation problem is strictly proper and minimum phase, assuming for each output measurement constraint one available actuator and the first Markov parameter to be full rank. This neces...
