The article summarizes a comparison of numerous irregular low-density parity-check codes using a set of metrics such as girth, number of short cycles in Tanner graph and extrinsic message degree (EMD). Based on this these metrics, we analyze how to decrease error floor for such codes with no negative effect to threshold.

This paper describes the information system, which has been developed for the storing and automated processing of the Soil Moisture and Ocean Salinity (SMOS) Level 1C radiometric and Level 2 soil moisture data over space and time. The information system contains the database for storing the data and the interface for automated processing. That interface has been developed to provide access to these specific data from the database within the Matlab numerical computing environment used for the realization of algorithms and methods. The developed information system helps to speed up the processing of SMOS data in regional scale over a long period of time, and has successfully been used for the validation of soil temperature and moisture retrieval algorithms over the North Slope of Alaska and Yamal peninsula.

The article presents a study of the Particle Swarm optimization method for scheduling problem. To improve the method's performance a restriction of particles' velocity and an evolutionary meta-optimization were realized. The approach proposed uses the Genetic algorithms for selection of the parameters of Particle Swarm optimization. Experiments were carried out on test tasks of the job-shop scheduling problem. This research proves the applicability of the approach and shows the importance of tuning the behavioral parameters of the swarm intelligence methods to achieve a high performance.

The paper proposes some new expressions in several coordinate systems (oblique-angled 60- and 120-degree coordinates, barycentric and affine coordinates on triangles) for the voltage space vector of the multilevel voltage source inverter. The offered space vector representations can be useful for the real time digital signal processor control of converters, some of them lead to the algorithmic simplifications.

A new universal technique for communication signal parameter estimation of a software defined radio system with an arbitrary multi-port receiver based on solution of its quadric equations by the maximum likelihood method is proposed. The expressions for error matrix of estimating parameters are obtained in linear approximation that allows one to investigate analytically the uncertainties of estimaiton. An optimisation method of multi-port junction parameters for measurement in very wide frequency range is described. The results of computer simulation confirming the theoretical conclusions are given.

This paper describes the design and measurement of a square-law microwave transistor detectors for wideband radiometers. To increase detector dynamic range a negative feedback was used in it. Theoretical analysis and CAD harmonic balance simulation were performed to optimize the detector circuit and find the optimal value of the feedback factor. Two variants of the detector were developed: on BJT and on FET transistors. Experimental hybrid circuits have been realized with discrete transistors, lumped elements and microstrip transmission lines. Results of measurement of detector main characteristics are given: transfer function, tangential sensitivity, dynamic range, frequency response, input VSWR. Dynamic range up to 55 dB was achieved (at 1 dB compression point and 1 kHz video-bandwidth) with flat frequency response up to 4 GHz. These square-law detectors may be used for precision measurements of microwave power, for example in modulation-type wideband microwave radiometers.
