Channel Versus System Innovation in Person/Person Telecommunications

Human Factors: The Journal of the Human Factors and Ergonomics Society, 1973
The most basic human factor in the design of a person/person telecommunications device is the question of whether the device is likely to fulfil human communication needs in a cost-effective fashion. To answer this question, it is necessary to identify the various alternative types of devices which could be developed.

A programmable CMOS dual channel interface processor for telecommunications applications

IEEE Journal of Solid-State Circuits, 1984
A CMOS analog VLSI chip for telecommunications applications has been designed in which many desirable line card features are programmable through a unique interface from the central switching office. The authors emphasize the circuit innovations of some key analog functions realized on the chip, specifically, the operational amplifier family, the ...

OPTICAL COMMUNICATION CHANNEL FOR UNDERWATER TELECOMMUNICATIONS

Informatization and communication
The article presents the results of an experiment on the use of a laser underwater communication system. The choice of optical wireless communication technology is substantiated. The method for calculating the range of the system takes into account the interfering effects of the aquatic environment and contains practical results when observing test ...

Neuro-fuzzy networks in adaptive coding of telecommunications channels

PeachFuzz 2000. 19th International Conference of the North American Fuzzy Information Processing Society - NAFIPS (Cat. No.00TH8500), 2002
Within the paper a system that controls the adaptive coding scheme of time varying telecommunications channels is presented. It is implemented by Berenji's neuro-fuzzy network GARIC (Generalized Approximate Reasoning-Based intelligent Control). A major advantage of this approach is that the system does not rely on any specific model of the channel ...

The causes of distribution channel conflict in Chinese telecommunication industry

2004 IEEE International Engineering Management Conference (IEEE Cat. No.04CH37574), 2005
Until now, there are some literatures discussing the conflict causes in western theory, especially in US theory. However, the differences between the situations of Chinese channel and western channel are neglected. In fact, the difference between them is important.

Channel Estimation and Interpolation for Fourth Generation Mobile Broadband Telecommunications

IFAC Proceedings Volumes, 2014
Abstract This paper studies the problem of channel estimation for the downlink in broadband LTE communications. A Kalman Filter is used to combine channel soundings made with pilot tones that are deployed at different times and in different frequency bands on a pre-selected pattern.

A Hybrid Genetic Approach for Channel Reuse in Multiple Access Telecommunication Networks

IEEE Journal on Selected Areas in Communications, 2000
The evolving broadband integrated services digital network is reinforcing the demand for high-speed and high-performance multiple access networks. The number of channels available to support the isochronous traffic in these networks is limited by technology, due to implementation costs.

Telecommunication systems on power distribution networks: high frequency performances of carrier channels

IEEE Transactions on Power Delivery, 1994
In the framework of a project aimed at the design and installation of a new extensive distribution automation system in the ENEL SpA (Italian National Electricity Company) distribution network, this paper presents the investigations carried out to check the feasibility of a line carrier system on the primary (medium voltage 10-30 kV) network.

Congressional--Constituent Telecommunication: The Potential and Limitations of Emergent Channels

IEEE Transactions on Communications, 1975
The study reported here undertakes an exploratory inquiry into the potential use of selected emergent telecommunication channels for communication between congressmen and their constituents. The potential and limitations of each channel are identified through interviews with a stratified judgment sample of U. S.

Telecommunication application modelling with multi writer multi reader Channels: a Case S

2008 Forum on Specification, Verification and Design Languages, 2008
Telecommunication applications require an increasingly high throughput; their task graph often exhibits a high level of coarse grained parallelism. We extend the KPN model by multiple writers and readers and present the SystemC based co-design of a packet classification application on a multi processor system on chip.
