systems of signals generating and processing in the field of on board communications

作者： O. G. Morozov A. Zh. Sakhabutdinov D. N. Matveev I. I. Nureev K. A. Khodjanepesov Kazan National Research Technical University named after A.N. Tupolev-KAI Kazan Russia Institute of Telecommunications and Informatics of Turkmenistan Ashgabat Turkmenistan

The development and use of on-board photovoltaic panels (PVP) makes it possible to improve the energy supply of unmanned or manned aerial vehicles, which are respectively positioned, for example, as flying base stations or vehicles with on-board batteries with a large energy reserve, capable of carrying more payload during long flights. The efficiency of a photovoltaic element (PVE) is seriously affected by clouds, blocking solar radiation, possible contamination or precipitation accumulated on its protective coating, aging of the PVE material, and the most important parameter - temperature. The aging effects and to a greater extent their temperature, affect the current-voltage characteristics of the PVE, so an on-board measurement system for its performance parameters can provide valuable information for optimizing the power generation process. The article proposes a methodology for monitoring the temperature of PVE and PVP in whole, which provides determination of their temperature over an area based on networks of fiber-optic sensors (FOS) and their addressed interrogation using a microwave-photonic approach.

systems of signals generating and processing in the field of on board communications

作者： V. I. Volovach V. M. Artyushenko Volga Region State University of Service Togliatty Russia Technological University Korolev Russia

A method for detecting signals with a random moment of occurrence based on the algorithm of cumulative sums with a reflecting screen under the influence of non-Gaussian noise is presented. An example of detecting a signal exposed to non-Gaussian quasi-deterministic additive noise is used for obtaining the dependences of the probability of false detection on the value of the signal-to-noise ratio for different values of the detection threshold. An increase in the detection threshold value, as well as the value of the signal-to-noise ratio, leads to a decrease in the probability of false detection. It is shown that the case of coordinated noise has the highest probability of correct detection. The algorithm for detecting a signal against the background of pulse noise and fluctuating non-Gaussian noise is analyzed and curves for probability of correct detection are obtained. It is found that the mismatch of the cumulative sum algorithm and the real density of probability distribution of noise leads to a decrease in the probability of correct detection. It is shown that the cumulative sum algorithm allows not only to solve the problem of detecting a signal in real time, but is also simple enough to be used when solving some practical problems.

In this paper, a new a secure communication scheme using chaotic signal for transmitting binary digital signals is proposed and which is then implemented on a Digital Signal Processor (DSP) board. The method uses the idea of indirect coupled synchronization for generating the same keystream in the transmitter and receiver side. This chaotic keystream is applied to encrypt the message signal before being modulated with a chaotic carrier generated from the transmitter. Discrete chaotic maps, 3D Henon map and Lorenz system are used as transmitter/receiver and key generators respectively. The overall system is experimentally implemented in the TMS320C6713 DSK board using code composer and Simulink showing the successful message extraction thus proving the feasibility of the system in the DSP board. © 2010 IEEE.

At that moment the volume of transmitted data grows according to the exponential law through all available communication channels. In this regard, more and more often this leads to the need to work in data transfer mode at a speed higher than the Nyquist rate. In this article, resolution time theory is used to develop novel approach jitter analysis dependent on the data that contributes to the overall jitter in frequency selective channels with PAM-n-signals. A novel approach has the following features: 1) the computational complexity is sub-exponential in the amount of effective memory; 2) no restrictions associated with the shape of the pulse; 3) strict rule is given for estimating the channel memory when using PAM-n-signals, which does not use the rule of maximum a posterior probability

field Programmable Analogue Array (FPAA) technologies can offer an analogue platform for a vast number of applications, including communication circuits requiring adaptive processing. The subject of this paper deals with the problem of generating and processing of base-band communication signals using a reconfigurable platform based on FPAA technology. In the experiments it was used AN221E04 circuit included in Anadigmvortex - AN221K04 development board and connected to PC through a serial interface. Also it was used the software tools from AnadigmDesigner2 that allows complex circuits to be designed with a simple drag-and-drop graphical interface. Especially analog modulators and demodulator were implemented, but the capabilities ofthe circuits offer great possibilities for more elaborated modulation schemes.

The model of distributed power amplifier, built on field-effect transistors of model MRF 9045, is presented. AM -AM characteristic and AM - PM characteristic investigated on the basis of this amplifier circuit are presented. The construction of a distributed power amplifier circuit for simplified modeling of parametric nonlinear distortion is discussed. Simplified models of this type of amplifiers for the HF and UHF ranges are given. In a simplified model for the HF range, the parametric capacitances are built on the basis of the capacitance-voltage characteristics on the field-effect transistor of model BLF 278. In the simplified model for the UHF range, the parametric capacitances are built on the basis of the capacitance-voltage characteristics on the field-effect transistor of model MRF 9045. The features of constructing a simplified model of a distributed gain amplifier are discussed. On the basis of simplified models of parametric nonlinear distortion amplifiers, several cases of the influence of parametric capacitances are investigated such as: the influence of the input parametric capacitance, as well as the influence of the output parametric capacitance. The result of the research is the amplitude and phase-amplitude characteristics. The reasons for parametric nonlinear distortions and methods of their linearization are discussed. Further research tasks are presented.

In the paper the problem of applying the digital antenna arrays (DAA) equipped with the directional radiators is considered simultaneously on azimuth and elevation planes. The method MUSIC of direction-of-arrival (DOA) estimation is researched depending on the shape of the antenna array and the directivity of an individual element. The half-dodecahedron, planar and cylindrical antenna arrays are considered. As it is well known along with DOA-estimation as the first step the beamforming is highly needed at the final stage of the digital arrays functionality. The optimal algorithm of maximizing the ratio of the useful signal to interference + noise (SNIR) is researched in the tasks of the radiation pattern formation simultaneously on azimuth and elevation planes. The estimations of the signal to noise and interference ratio as well as bit error rate (BER) are obtained depending on the directivity of the emitters. The research has established that the shape of the radiation pattern of elements has a significant impact on both the accuracy of bearings and placing the main lobe and zeros. The curves are provided showing the optimal performance of DAA on azimuth and elevation planes.

Despite the widespread development of satellite mobile communications, radio communications in the high frequency range (3 - 30 MHz) retains its position when it is necessary to ensure over-the-horizon data transmission with low delays. The transmission speed of samples from the world's leading manufacturers reaches 120 kbit/s with a used radio channel width of 24 kHz. Manpack radios place high demands on weight and size characteristics, which are largely determined by the efficiency of the most energy-intensive unit - the power amplifier (PA). The article analyzes ways to increase the PA efficiency taking into account the features of modern telecommunication signals that use amplitude-phase modulation and have a large crest factor. Based on a preliminary analysis of a wide range of directions for increasing the radio frequency amplifiers efficiency, the most promising options for the problem under consideration are selected: a power amplifier with envelope elimination and restoration (EER) and an amplifier using the outphasing method. To date, the theoretical issues of constructing the EER PA and the prospects for its practical implementation have been better developed. At the same time, the potential capabilities of a transmitter built using the outphasing method are higher than those of the EER PA, since it does not have an inertial low-frequency envelope path, which reduces both energy performance and limits the possibility of improving quality characteristics. A conclusion is made about the advisability of further research, modeling, prototyping and testing of the transmitter using the outphasing method.
