RSS rate estimationPath Selection Using Available Bandwidth Estimation in Overlay-Based Video Streaming
White Paper IP networks present a challenging environment for video streaming because they do not provide throughput, jitter, or loss rate guarantees. The path selection is based on the measurement of network-layer metrics, such as... [10 Sep 2008]
Analysis of Decision-Feedback Based Broadband OFDM Systems
White Paper In wireless communications, about 25%of the bandwidth is dedicated to training symbols for channel estimation. However, semi-blind approach can significantly deteriorate the performance if the bit error... [11 Aug 2008]
pathChirp: Efficient Available Bandwidth Estimation for Network Paths
White Paper Since it uses only packet interarrival times for estimation, pathChirp does not require synchronous nor highly stable clocks at the sender and receiver. By rapidly increasing the probing rate within each... [11 Jul 2008]
A Two-Stage Plug-in Bandwidth Selection and Its Implementation for Covariance Estimation
White Paper The two most popular bandwidth choice rules for kernel HAC estimation have been proposed by Andrews (1991) and Newey and West (1994). It is shown that the optimal bandwidth for the kernel-smoothed normalized curvature... [11 Jul 2008]
An Iterative Approach to Optimal Non-Uniform Sampling and Instantaneous Bandwidth Estimation
White Paper The proposed method is based on estimation of a time-distortion transformation, under which the original signal becomes bandlimited and can thus be reconstructed. The estimation is iterative, and can be... [11 Jul 2008]
