The new method of decision-feedback parameters optimization for intersymbol interference equalizers is described in this paper. The error extension phenomena is well known and investigated in the decision feedback equalizers in data transmission. The existing coefficient in decision feedback depends on the receive decision risk qualification. There is proved the bit error probability can be decreased by this method for any channel with single interference sample and small Gaussian noise. The experimental results are presented for chosen type channels. The dependences of optimal feedback parameters on channel interference sample and on noise power are presented too.

Bezprzewodowa łączność umożliwia bezawaryjną i niezawodną transmisję danych i sygnałów w połączeniu z szybką i ekonomiczną instalacją. W rezultacie bezprzewodowa komunikacja jest coraz częściej stosowana w automatyce przemysłowej. Poza standardami WLAN 802.11 b/g, które są stosowane zwłaszcza w infrastrukturach sieci LAN w budynkach fabrycznych, technologia Bluetooth rozwija się jako optymalne rozwiązanie w przypadku wielu zadań automatyzacji. Bluetooth jest znormalizowaną technologią łączności bezprzewodowej (IEEE 802.15.1), o uniwersalnym zastosowaniu, która jest zarazem niezawodna i stabilna.

Data communication is an important part in modern industrial processes and is necessary in automation, monitoring, and protection purposes. This paper aims at designing a real time communication between two computers for interchanging the state of a three phase circuit to emulate a transmission line protection system in power substation. The circuit designed in Proteus ISIS is based on "symmetrical component theory" and the algorithm for exchanging data between two computers is built using TCP/IP protocol in LABVIEW environment. The application consists of monitoring and controlling three phase lines by sending the data collected to one of the computers and sending the commands back to trip relays if any fault is detected. The purpose is to prevent the propagation of this fault and to connect other sources to maintain the flow of power to the load.

Multiple input multiple output power line communication is presented with its major characteristics and models. Orthogonal frequency division multiplexing modulation scheme applied to power line channel model is presented, also, combination of orthogonal frequency division multiplexing with MIMO Alamouti space time block codes to improve reliability and data rate performance of the system is done. The evaluation of the orthogonal frequency division multiplexing-PLC system over power line communication channel is performed. The comparison between simple PLC and MIMO-PLC systems based upon achieved data rates and reliability in terms of bit error rate is presented.
