This paper presents a speech-model using the Linear Predictive (LP) residual signal and Maximum Likelihood Estimator (MLE). With this model an accuracy of the reverberation time estimation can be improved. During past decade, the reverberation time estimation was performed using only maximum likelihood detector, which resulted in excess time of estimation. For the purpose of estimating room aco...

Likelihood ratio (LR) tests are provided for the three alternatives to DNA identity: exclusion, coincidence, and kinship. The coincidence test uses the radius of coalescence to conserve the observed frequency of single band phenotypes. Genotype probabilities under kinship are derived for mating groups, specified relatives, and structured populations; and unbiased estimates of the genetic parame...

Based on Time-Frequency (TF) analysis and a-contrario theory, this paper presents a new approach for extraction of linear arranged power transmission tower series in Polarimetric Synthetic Aperture Radar (PolSAR) images. Firstly, the PolSAR multidimensional information is analyzed using a linear TF decomposition approach. The stationarity of each pixel is assessed by testing the maximum likelih...

In this paper we introduce a high-resolution CFAR detector for the linear data model. The detector is derived using the generalized likelihood-ratio test (GLRT) framework. The resulting detector has a number of distinctive properties. One property of the detector is that it is most useful when the training and testing data contain the signal-of-interest. In fact, this detector does not need tra...

The maximum likelihood detection theory improves the error rate of a sub-optimal but cheaper, coded symbol recovery loop using oversampling proposed as an alternate solution for decoding problem without log-likelihood ratio computation. former implementation delivers output data in one-symbol delay, and required transistor count makes this approach attractive ultra-low-energy wireless applicati...

In the evaluation of speaker recognition systems, the tradeoff between missed speakers and false alarms has always been an important diagnostic tool. NIST has defined the task of speaker detection with the associated Detection Cost Function (DCF) to evaluate performance, and introduced the DET-plot [1] as a diagnostic tool. Since the first evaluation in 1996, these evaluation tools have been em...

We assume a linear equidistance antenna array as the receiver for a fixed frame-length multipleaccess system which employs variable-gain receiver power and repetition encoding. We propose a robust Maximum A posteriori Probability (MAP) Blind Bit-Rate Detector (BBRD). This detector considers the Rate Detection (RD) as a multi-hypothesis test and maximizes the Likelihood Functions (LF)s to find t...
