The paper proposes a model for estimation of perceived video quality in IPTV, taking as input both video coding and network Quality of Service parameters. It includes some fitting parameters that depend mainly on the information contents of the video sequences. A method to derive them from the Spatial and Temporal Information contents of the sequences is proposed. The model may be used for near real-time monitoring of IPTV video quality.

Mobile telecommunication is evolving rapidly. People no longer only communicate with each other regardless of time and place, but also share other information that is important for the tasks with which they are involved. In response to this growing trend, the Media Sense framework addresses the intelligent delivery of any information to any host, anywhere, based on context-aware information regarding personal preferences, presence information, and sensor values. The focus of this paper is the overall framework, the handling of user profiles, management of context information, real-time distribution and proof of concepts.

For emerging 40 Gb/s computer networks, we need devices that are capable of sustained line-rate operation for monitoring, test patterns generation and data stream processing. In this paper, we describe design options and our practical experience with developing such a platform for 40 Gb/s network. We present a working prototype for 40 Gb/s networks using SERDES Framer Interface Level 5 (SFI-5) communication protocol and prove that high speed network processing such as 40 Gb/s lines is possible with embedded system using an FPGA device.

In this paper, we present test result and practical analysis some of interoperability problems for PSTN emulation and simulation services. Before implementing next generation network, it is needed to provide a testbed for testing and evaluating vendor’s equipment. ITRC NGN pilot is a testbed that implemented in Iran Telecom Research Center (ITRC) and four vendors have participated in the pilot. The pilot realized that there were many fail in interoperability test area. The Pilot analyzed test result and realized that the problems have been caused by two main factors: some vendors do not implemented standards completely and there are some ambiguities in standards.

In this paper, we present a comparative analysisof three classifiers for speech signal emotion recognition.Recognition was performed on emotional Berlin Database.This work focuses on speaker and utterance (phrase)dependent and independent framework. One hundred thirtythree (133) sound/speech features were extracted from Pitch,Mel Frequency Cepstral Coefficients, Energy and Formantsand were evaluated in order to create a feature set sufficient todiscriminate between seven emotions in acted speech. A set of26 features was selected by statistical method and MultilayerPercepton, Probabilistic Neural Networks and Support VectorMachine were used for the Emotion Classification at sevenclasses: anger, happiness, anxiety/fear, sadness, boredom,disgust and neutral. In speaker dependent framework,Probabilistic Neural Network classifier reached very highaccuracy of 94%, whereas in speaker independent framework,Support Vector Machine classification reached the bestaccuracy of 80%. The results of numerical experiments aregiven and discussed in the paper.

In this paper, we investigate an efficient signal detection algorithm, which combines lattice reduction (LR) and list decoding (LD) techniques for the 3rd generation long term evolution (LTE) downlink systems. The resulting detector, called LRLD based detector, is carried out within the framework of successive interference cancellation (SIC), which takes full advantages of the reliable LR detection. Simulation results show that the proposed LRLD based detector provides a near maximum likelihood (ML) performance with a significantly reduced complexity.

This research deals with a study of case, unifying theoretical and practical aspects, regarding the cell-planning of Wideband Code Division Multiplexing (WCDMA) Release 99 (Rel99) and High Speed Downlink Packet Access (HSDPA) Rel. 5 networks. The used methodology, validated by the close agreement between field and numerical results for throughput and cell coverage, is a useful tool to have first order throughput/coverage prediction results for dimensioning and optimization purposes of advanced wireless networks. The field and analytical results also have confirmed that the HSDPA Rel. 5 allow a higher performance with a similar coverage in relation to that one obtained with a WCDMA Rel. 99 network.

The Future Battlefield Commander relies on Command, Control, Communications, Computers, Information, Intelligence (C4I2) tools to perform optimally in his given tasks in versatile and hostile environments. The concept of war has changed from traditional wars to the asymmetric wars. This paper describes main use cases of a new network concept, the Wireless Polling Sensor Network (WPSN) for the Dismounted Future Warrior. The appearance of Unmanned Vehicles (UVs) gives an edge to gain and transmit information from designated hostile areas to decision making process ensuring mission success and reduced fratricide. New principles determine how this new technology can be adapted in Future Warriors at different levels. The main use cases are solutions of this technology in road bomb detection, location in built up areas, and, finally, in Special Operations. This paper is based on a study of the main use cases of the WSPN and thereby discusses the usage principles, and the results representing the ideas of applying the WPSN technology. The three questions to be answered are: What is the structure of the WPSN like? What are the main advantages of the WPSN over the Wireless Sensor Network (WSN)? Which are the typical scenarios in which the WPSN can be benefitted of? Main output of the paper is to point out the possibilities to utilize the WPSN via use cases.

In this paper, we implement an automatic news text-to-speech broadcast system for mobility disabled elder. The RSS (rich site summary) format and website information of news titles are used and gotten. Every website of news will be abstracted, analyzed, and automatically text-to-speech broadcasted main text to elder. Simulation results show that the propose system is a better solution than general UI, such as remote controller.
