Currently, the telecommunications world is moving towards a greater degree of flexibility among different techniques and frequencies. By the way, the implementation via software of functions, generally implemented via hardware, is a crucial step, since software can allow improving reconfigurability, portability and interoperability between different kinds of systems. Global Navigation Satellite Systems (GNSS) can be considered, in this context, a significant example. In fact, the GNSS world offers, nowadays, a lot of different systems already in use, in phase of testing or in phase of implementation. A receiver able to work with different systems with no hardware modifications is therefore fundamental. This paper aims at describing the SDR technique, the state of the art of the SDR GNSS receivers and the improvements achieved by us in terms of testing new functions and future ideas.

This paper presents some experimental results of unusual propagation of an ultra wide band pulse in low-voltage installation three-conductor power cables. For cables of flat cross section, the results confirm the possibility of modal decomposition of a pulse into two low level pulses. However, this phenomenon does not appear in cables of circular cross section.

This paper considers the problem of electing a leader in dynamic peer-to-peer systems in which nodes behavior in high rate of churn. Usually the leader node is used to coordinate some tasks. Leader election influences on the performance of the system in two stages; the election operation and the result of the election as example leader's ability in making its responsibilities. Because of the Peer-to-Peer systems is high dynamic, it was focus on the first stage in order to elect the leader with high efficient method. So, the proposed algorithm is with complexity O(1). In algorithm, the election operations are dependent only on local knowledge. The correctness of the algorithm is analytically proved and its scalability and efficiency experimentally are evaluated by using simulations.

In this paper we develop innovation-based adaptive Kalman filter (IAKF) based on linear time-varying (LTV) state-space model. Thorough argumentation of process and measurement noise covariance adaptation based on innovation sequence covariance is provided. As a result of implementing the proposed methods the process noise and measurement noise covariance matrices are adapted within a sliding window of a fixed depth.

Preliminary accounts and experiments for clarification of the creation opportunity of matrix X-ray gallium arsenide detector with embed electronics were made. It is revealed, that efficiency of charge collection in this detector will be higher than the selenium prototype. Also it is revealed, that detector channel resistance can exceed 1000 GOhm, and storage capacitor and transistor closed channel resistance can be made higher than 100 GOhm that is essential and sufficient for proper circuit work.
