Evaluation of international standards for ECG-recording and storage for use in tele-medical services
(Research report, 2006-05-16)This report is written to clarify which of the international standards for ECG recordings that can be used in tele-medical services, where the recordings should be transmitted by wireless telecommunication facilities and ... -
Remote Service Usage Through Sip with Multimedia Access as a Use Case
(Journal article; Peer reviewed, 2007)The IP Multimedia Subsystem is under deployment, as an IP-based service control and access infrastructure, but how it interconnects with residential appliances is currently unclear. With IMS access for the residential ... -
Using SIP Presence for Remote Service Awareness
(Chapter; Peer reviewed, 2008)Residential networks usually protect its devices and services behind firewalls and use private IP addresses. Therefore, appliances within a residential network cannot be discovered and utilized from external networks by ... -
Phone-Controlled Delivery of NGN Services into Residential Environments
(Journal article; Peer reviewed, 2008)The horizontally layered architecture of the IMS/NGN standards family enables the delivery of services independent of access network and requesting device. In this article, the authors propose a further separation of service ... -
Delivering Services to Residential Appliances by Utilizing Remote Resource Awareness
(Journal article; Peer reviewed, 2008)Service providers are nowadays offering a variety of services, and in particular multimedia content delivery. Besides, consumer appliances are increasingly becoming digitalized including support for communication networks. ... -
Categorizing networked services The role of intrinsic-, user network- and complement network attributes
(Journal article, 2009)Originality/value - The paper contributes with a conceptual framework for understanding and categorizing both extrinsic and intrinsic drivers of service value. It extends and integrates previous work on network effects and ... -
The influence of LOS components on the statistical properties of the capacity of amplify-and-forward channels
(Journal article; Peer reviewed, 2009)Amplify-and-forward channels in cooperative networks provide a promising improvement in the network coverage and system throughput. Under line-of-sight (LOS) propagation conditions in such cooperative networks, the overall ... -
Parameter optimization for amplify-and-forward relaying systems with pilot symbol assisted modulation scheme
(Journal article; Peer reviewed, 2009)Cooperative diversity is a promising technology for future wireless networks. In this paper, we consider a cooperative communication system operating in an amplify-and-forward (AF) mode with a pilot symbol assisted modulation ... -
A study of the influence of shadowing on the statistical properties of the capacity of mobile radio channels
(Journal article; Peer reviewed, 2009)This paper studies the influence of shadowing on the statistical properties of the channel capacity. The problem is addressed by using a Suzuki process as an appropriate statistical channel model for land mobile terrestrial ... -
Exact closed-form expressions for the distribution, the level-crossing rate, and the average duration of fades of the capacity of OSTBC-MIMO channels
(Journal article; Peer reviewed, 2009)This paper deals with some important statistical properties of the channel capacity of multiple-input-multiple-output (MIMO) systems with orthogonal space-time block code (OSTBC) transmission. We assume that all the ... -
On the problems of symbol-spaced tapped-delay-line models for WSSUS channels
(Peer reviewed; Journal article, 2009)This paper analyzes the validity and statistical behavior of symbol-spaced tapped-delay-line (SSTDL) models for wide-sense stationary uncorrelated scattering (WSSUS) mobile radio channels. SSTDL models are obtained by ... -
Two new sum-of-sinusoids-based methods for the efficient generation of multiple uncorrelated rayleigh fading waveforms
(Journal article; Peer reviewed, 2009)This paper deals with the design of a set of multiple uncorrelated Rayleigh fading waveforms. The Rayleigh fading waveforms are mutually uncorrelated, but each waveform is correlated in time. The waveforms are generated ... -
A dynamic parallel-rendezvous MAC mechanism in multi-rate cognitive radio networks: Mechanism design and performance evaluation
(Journal article; Peer reviewed, 2009)Parallel rendezvous multi-channel MAC mechanisms are regarded as an efficient method for media access control in cognitive radio networks since they do not need a control channel and use only one transceiver. ... -
