This contribution describes a fast frequency domain approach for blind channel identification which does not rely on the statistic of the symbols. The proposed approach is based on the so–called “intraspectral relations” of DFT’s of PAM fractionally sampled signals. The use of DFT’s is allowed under certain conditions commonly encountered in data communication systems. The intraspectral relatio...

Flow-through respirometry systems provide accurate measurement of gas exchange over long periods of time. However, these systems have limitations in tracking rapid changes. When an animal infuses a metabolic gas into the respirometry chamber in a short burst, diffusion and airflow in the chamber gradually alter the original signal before it arrives at the gas analyzer. For single or multiple bu...

I use a novel monthly panel of provincially-collected central government revenues and conflict fatalities to estimate lost due in Afghanistan since 2005. Headline estimates are large, implying total revenue losses $3bn 2005 that gains from peace would have been about 6 percent GDP per year. That this is larger than cross-country studies reflects the uncommon intensity Afghanistan. The key chall...

In this paper, I compare model-based and moving average-based approaches to seasonal adjustment. I propose an optimal moving average filter, designed to minimize the distance from a model-based filter. In simulations, I consider the accuracy of the alternative methods in estimating seasonal factors in a simple model. I find that the most reliable results are obtained either by the model-based a...

In this paper, we derive the impulse response of a fractional second order filter of the form ðs2þasþbÞ g, where a; b 0 and g40. The asymptotic properties of the impulse responses are obtained. Moreover, based on the derived analytical impulse response, we show how to perform the discretization of the above fractional second order filter. Finally, a number of illustrated examples in time and fr...
