Item Efficiency increase of information services in 3G and 4G networks, using MIMO-systems(Видавництво Львівської політехніки, 2012) Yaremko, OlegThe basic idea of a CDMA system to overcome the multipath problem is built on the fact that a spread spectrum signal has a much wider bandwidth occupancy than its original baseband signal, such that the spread spectrum signal will offer a unique property that multipath diversity can be made possible due to its excellent time resolution derived from its very wide bandwidth signaling. A RAKE receiver can be used to resolve different multipath returns individually and combine them again in a coherent or non-coherent way, to achieve the multipath diversity capability, which has become one of the most important technical features that make CDMA a very attractive multiple access technology for 2G and 3G wireless communications.Item Intelligent resource allocation of service-oriented networks(Видавництво Львівської політехніки, 2012) Schill, Alexander; Gütter, Dietbert; Yaremko, OlegThe offered paper discusses important development trends for a CAD for network planning regarding to the tool integration and access. CANDY Framework and Online Platform as a reference system are examined. The CANDY System has been represented as an exhibit at CeBIT 2007, 2008, 2011 in Hannover (Hall 9/Stand D04).Item The systems of set about a reception are on the basis of MIMO of antennas(Видавництво Львівської політехніки, 2010) Yaremko, OlegFor the off-wire dustings of connection the negative consequences of stoppings beating of signal, waves caused multiband distributions are considered. The features of set about a reception, realized by the use of a few aerials on a receiving side are considered. Comparison of different methods of combining of initial signals of separate aerials is conducted and recommendations are given from their application.Item Wavelength routed optical neural networks(Видавництво Львівської політехніки, 2012) Dymich, Stepan; Kaidan, Mykola; Strykhaluik, Bogdan; Yaremko, Oleg; Melnyk, OksanaIn this paper wavelength routed optical neural networks are presented. Characteristics of low-oriented models of routing were classified.
