Heisenberg Security at your service: Researchers at the University of Toronto have developed a new technique using photons to keep your data safe when transmitted over a fiber-optic cable. They based their research on Heisenberg's Uncertainty Principle and used photonic 'decoys' to encrypt data over distances of 15 kilometers. By mixing these photon keys with...; Tags: technique, Hoi-Kwong Lo, quantum key distribution; Blog posts 2006-02-26
Negotiation-Based Service-Oriented Software Process in Peer-to-Peer Environments: Among many emerging technologies, service-oriented architecture and peer-to-peer networking are significantly changing not only the properties of applications, but the way to develop them. In this paper, the authors envision a convergence of these two - peer service systems. However, how to efficiently develop distributed applications in such peer service...; Tags: P2P, University Of Toronto, Negotiation, Peer To Peer (P2P), Free Trade, Service-Oriented Architecture (SOA), Internet, Finance, Web Services, Enterprise Software, Software; White papers 2005-12-26
The WebMonkey Project: The primary objective of the project discussed in this paper is to create a semi-autonomous browsing interface whereby independent browsers, operating on different virtual machines, are securely controlled by an external source, be it a human or a script. There is no general definition of what constitutes Spyware. It is...; Tags: Credit Card, XUL, University Of Toronto, Spyware, Spyware, Adware & Malware, Cyberthreats, XML, Web Browsers, Viruses And Worms, Security, Software/Web Development, Web Development, Internet; White papers 2005-10-06
Spatio-Temporal Schedulers in IEEE 802.16: With the growing interest in Broadband Wireless Access BWA and demand for mobile high-speed connection, there is a need to extend wireless connectivity to passengers travelling in high-speed vehicles. In this paper, the IEEE 802.16 standard is used as a backhaul communication technology for broadband wireless access to railway systems....; Tags: Base Station, Mobile, Broadband Wireless, IEEE 802.16, Wireless Access, University Of Toronto, WiMAX, Broadband Internet, Wireless, Advertising & Promotion, Telecommunications, Marketing; White papers 2005-08-31
An Introduction to Multicarrier Modulation: Multicarrier modulation helps to reduce the detrimental effects of multipath fading. Because of its robustness to multipath, and the ease of implementing it in transmitters and receivers using the Fast Fourier Transform FFT, the MCM concept is growing rapidly in practical importance. It can be found today in IEEE standards...; Tags: Modulation, Multipath, University Of Toronto, WiMAX, Wireless LANs, Wireless; White papers 2005-05-31
Adaptive Channel SVD Estimation for MIMO-OFDM Systems: In this paper an adaptive estimation algorithm for channel matrix singular value decomposition SVD in multiple-input multiple-output MIMO orthogonal frequency division multiplexing OFDM systems is proposed. The SVD method is an efficient approach to design space-time coding/decoding and detection algorithms in MIMO-OFDM systems. However, the SVD estimation may involve complex...; Tags: Estimation, Algorithm, MIMO-OFDM, University Of Toronto, Singular Value Decomposition Method, OFDM, Engineering, Wireless; White papers 2005-05-07
Service Level Management: Optimizing Your OSS for SLA Delivery: As the Telecommunication world move from the circuit switching to packet switching and from the dedicated circuit to IP VPN, QoS, Service Level Management is becoming more and more vital when the service provider deals with customers.

The Need for Cross-Layer Service Discovery in MANETs: Service selection has a crucial effect on wireless multi-hop ad hoc network MANET performance. Because of the broadcast nature of wireless transmission, good service selection groups clients with nearby service providers, localizing communication, which in turn reduces inter-node interference and allows for multiple concurrent transmissions in different parts of the...; Tags: Network, University Of Toronto, Service Discovery, Service Selection, Networking; White papers
Multi-Campus Wireless Network Liberating University of Toronto Students: The University of Toronto sought a solution that would truly free its degree seekers and allow them to study wherever and whenever they find most beneficial.

Improved Correlation-Based Channel Estimators for DS-CDMA: Channel estimates obtained using the conventional correlation-based approach are biased when short spreading sequences are employed in CDMA systems. In addition, they suffer from Inter-Path Interference IPI due to the non-zero autocorrelation values of typical spreading sequences. For long-code systems, sometimes known as aperiodic spreading, the estimates are unbiased but...; Tags: University Of Toronto, Productivity, Performance Management, Cellular Phones, Human Resources, Workforce Management, Consumer Electronics, Personal Technology; White papers
