This document is a hands-on of Maple worksheet for automatic code generation and simulation system for nonlinear model predictive control (NMPC) . This method is well known as a fast algorithm and expected to real-time implementation in a system. This describes the components and usage of the automatic code generation system named "AutoGenU for Maple". This worksheet is required Maple 17 or lat...

The aim of this paper is to examine the effects of the nonlinear distortions introduced by high-power amplifiers (HPAs) in the downlink of direct-sequence code-division multiple-access (DS-CDMA) systems. By modelling the nonlinear distortion noise as coloured Gaussian noise, a semi-analytical expression for the symbol-error rate (SER) of linear multiuser detectors (LMDs) in frequency-selective ...

The crest factor properties of binary phase-shift keying modulated twoand four-code assisted multicarrier code-division multiple-access (MC-CDMA) employing complementary-sequence-based spreading sequences are characterized. More specifically, a complementary-sequence pair, a complementary-sequence-based subcomplementary code pair, and a Sivaswamy’s complementary code set are studied. It was fou...

It is known that some good linear codes over a finite ring (R-linear codes) arise from interesting point constellations in certain projective geometries. For example, the expurgated Nordstrom-Robinson code, a nonlinear binary [14, 6, 6]-code which has higher minimum distance than any linear binary [14, 6]-code, can be constructed from a maximal 2-arc in the projective Hjelmslev plane over Z4. W...

This paper presents the virtual laboratory software developed at the Department of Mathematical Modeling (BMSTU). The laboratory is designed as an educational tool for the nonlinear control courses. It allows to see 3D demonstrations of control processes for various nonlinear systems. The laboratory software package is developed using the Python programming language. It has open code and archit...

In this paper we give the results found in solving consistent sparse systems of nonlinear equations by an inexact Newton and Quasi-Newton method both combined with a block iterative row-projection linear solver of Cimmino-type. A simple partitioning of the Jacobian matrix was used for solving two nonlinear test problems, that is a tridiagonal problem of size n = 131072 and a nonlinear Poisson p...

In this paper we compare the performance of two codes for convex 0-1 mixed integer nonlinear programs on a number of test problems. The rst code uses a branch and bound algorithm. The second code is a commercially available implementation of an outer approximation algorithm. The comparison demonstrates that both approaches are generally capable of solving the test problems. However, there are s...

The Nordstrom-Robinson code, a nonlinear binary code of length 16 and minimal Hamming distance 6, is the binary image of the octacode, a linear self-dual code over 4 of length 8 and minimal Lee distance 6. Since the octacode is the 4-analogue of a Hamming code, this provides an extremely simple definition of the Nordstrom-Robinson code. A different version of this paper appeared in: Coding and ...

The study in this paper underlines the importance of correct joint selection of the spreading codes for uplink of multicarrier code division multiple access (MC-CDMA) at the transmitter side and detector at the receiver side in the presence of nonlinear distortion due to high power amplifier (HPA). The bit error rate (BER) of system for different spreading sequences (Walsh code, Gold code, orth...
