In this paper we propose an extension of the three-parameter Burr III distribution with the consideration of both theoretical and practical reasons. The research is motivated by low-flow frequency analysis in water resources research. Three commonly used parameter estimation methods were evaluated, including the method of moments, probability-weighted moments (or L-moments) and maximum likeliho...

With the Lv’s distribution (LVD), the chirp rates of linear frequency modulated (LFM) signals can be more accurately estimated for the local polynomial periodogram (LPP). Comparing to the estimation methods based on the polynomial Fourier transform (PFT) and fractional Fourier transform (FrFT), it is shown that LPP with the chirp rate estimated by LV’s distributioneffectively obtains better per...

We address a new integer frequency offset (IFO) estimation scheme with an aid of a pilot for orthogonal frequency division multiplexing systems. After correlating each continual pilot with a predetermined scattered pilot, the correlation value is again correlated to alleviate the influence of the timing offset. From numerical results, it is demonstrated that the influence of the timing offset o...
