RSS estimationRobust Control Tools for Traffic Monitoring in TCP/AQM Networks
White Paper Hence, appropriate robust control tools as quadratic separation are adopted to construct a delay dependent observer for TCP flows estimation. Several studies have considered control theory tools for traffic control in... [02 Oct 2009]
CFR and SNR Estimation Based on Complementary Golay Sequences for Single-Carrier Block Transmission in 60-GHz WPAN
White Paper However, MMSE-FDE needs the estimation of both the Channel Frequency Response (CFR) and the Signal-to-Noise Ratio (SNR). Through simulations, one proved that the proposed CFR and SNR estimation methods... [30 Aug 2009]
Data-Mining Discovery of Pattern and Process in Ecological Systems
White Paper Most ecologists use statistical methods as their main analytical tools when analyzing data to identify relationships between a response and a set of predictors; thus, they treat all analyses as hypothesis tests or exercises in parameter... [29 Aug 2009]
