Frequency intersystem interference is a phenomenon caused by coexistence of multiple wireless systems in same or adjacent areas. Consequently, frequency sharing studies play a very important rule in order to use limited spectrum resources efficiently. Because an International Mobile Telecommunication-Advanced (IMT-Advanced) systems are going to use 3500 MHz according to World Radiocommunication...

Coexistence of various wireless systems may cause frequency intersystem interference problems. Consequently, frequency sharing studies play a very important task in order to use limited spectrum resources efficiently. Because an International Mobile Telecommunication-Advanced (IMT-Advanced) systems are going to use 3500 MHz according to World Radiocommunication Conferences 2007 (WRC-07) decisio...

The telecommunication industry has been developing at a very fast rate, but data networking service revenue has continued to rise. This paper presents on performance enhancement of the WiMAX system (Worldwide Interoperability for Microwave Access) by using Adaptive Equalizer. WiMAX is an emerging global broadband wireless system based on IEEE 802.16 standards. It is a new wireless OFDM-based te...

An approach to determining the bandwidth of self-healing segment data network is proposed. The subject study are autonomous segments telecommunications network, which have property self-healing. object research process information transfer between nodes an segment. scientific novelty improve method capacity with limited resources by applying criterion ensuring minimum time delivery at a given l...

Orthogonal Frequency Division Multiplexing (OFDM) is a multi-carrier scheme used in modern broadband wireless communication systems to transmit data over a number of orthogonal subcarriers. When transmitted signals arrive at the receiver by more than one path of different length, the received signals are staggered in time; this is multipath propagation. To mitigate the effect of dispersed chann...

FOREWORD The ITU-T (Telecommunication Standardization Sector) is a permanent organ of the International Telecommunication Union (ITU). The ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Conference (WTSC), which meets e...

Conventional manual approach to DSP code generation usually takes the major manpower allocation in telecommunication design. A retargetable DSP code generation methodology based on SUIF is therefore proposed to address this problem in Fujitsu telecommunication design environment. This automatic code generation ow is brieey reported in this paper. Some essential code generation issues speciic to...

User requirements for telecommunication systems are difficult to understand because they are obscured by a long history of ad hoc feature development and technological limitations. The presence of a viable modular architecture for telecommunication features gives us a fresh start. Working within this framework, we can discover desirable properties that ought to be requirements for all telecommu...
