| In the narrow band array processing context, the use of higher-order statistics has been often advocated because consistent and asymptotically unbiased parameter estimates can be obtained without it being necessary to know, to model or to estimate the spatial covariance of the noise as long as it is normally distributed. However, experimentation shows that this`noise insensitivity' is traded ...

Over the last fifty years, How to Lie with Statistics has sold more copies than any other statistical text. This note explores the factors that contributed to its success and provides biographical sketches of its creators: author Darrell Huff and illustrator Irving Geis.

The demand of communicating at higher data rates can be easily met by using wideband signals [1], rendering the problem of estimating the direction of arrival (DOA) of wideband sources quite important. Multipaths, scatterers etc. present near the transmitter provide spatial bandwidth to these sources, which seriously degrade the performance of traditional DOA estimation techniques, designed ass...

A new pseudo-noise resampling technique is proposed to mitigate the effect of outliers in Unitary ESPRIT. This scheme improves the performance of Unitary ESPRIT in unreliable situations, where the so-called reliability test has a failure. For this purpose, we exploit a pseudo-noise resampling of a failed Unitary ESPRIT estimator with a censored selection of “successful” resamplings recovering t...

In this paper, noncoherent receivers for differential space–time modulation (DSTM) are investigated. It is shown that the performance of the previously proposed conventional differential detection (DD) receiver is satisfactory only for very slow flat fading channels. However, conventional DD suffers from a considerable loss in performance even for moderately fast fading. In order to overcome th...

Preparing the books to read every day is enjoyable for many people. However, there are still many people who also don't like reading. This is a problem. But, when you can support others to start reading, it will be better. One of the books that can be recommended for new readers is narrowband direction of arrival estimation for antenna arrays narrowband direction of arrival estimation for anten...

In this paper, our focus of attention is the proper propagationof fuzzy degrees in determinization of $Nondeterministic$ $Fuzzy$$Finite$ $Tree$ $Automata$ (NFFTA). Initially, two determinizationmethods are introduced which have some limitations (one inbehavior preserving and other in type of fuzzy operations). Inorder to eliminate these limitations and increasing theefficiency of FFTA, we defin...
