Capacity and Impedance Estimation by Analysing and Modeling in Real Time Incremental Capacity Curves

Video receiver based real-time estimation of channel capacity

This paper examines the problem of real-time estimation of the capacity, which is also known as the bottleneck bandwidth, of a network path using end-to-end measurements in a video streaming application. We utilize two basic packet-pair bandwidth-sampling methods and show how they can be applied in real-time to the video traffic. We then examine the performance of both sampling methods in a num...

Analysing Capacity Improvements in Wireless Networks by Relaying

Time dependent ROC curves for the estimation of true prognostic capacity of microarray data.

Microarray data can be used to identify prognostic signatures based on time-to-event data. The analysis of microarrays is often associated with overfitting and many papers have dealt with this issue. However, little attention has been paid to incomplete time-to-event data (truncated and censored follow-up). We have adapted the 0.632+ bootstrap estimator for the evaluation of time-dependent ROC ...

Integrating Security and Real-Time Requirements Using Covert Channel Capacity

ÐDatabase systems for real-time applications must satisfy timing constraints associated with transactions in addition to maintaining data consistency. In addition to real-time requirements, security is usually required in many applications. Multilevel security requirements introduce a new dimension to transaction processing in real-time database systems. In this paper, we argue that, due to the...

Real-time Multi-user MIMO Channel Sounding and Capacity Evaluations

In multi-user multiple-input multiple-output (MU-MIMO) systems, spatial multiplexing can be employed to increase the throughput without the need for multiple antennas and expensive signal processing at the user equipments. In theory, MU-MIMO is also more immune to most of propagation limitations plaguing single-user MIMO (SU-MIMO) systems, such as channel rank loss or antenna correlation. In th...
