Until better measures have been accepted for wider use, the Mini-Mental State Examination (MMSE) will continue to be utilized. In this context, knowledge on characteristics and determinants of its distribution for the Brazilian population are particularly valuable. The present study aimed to evaluate, based on multivariate analysis, the independent effect of age, educational level and sex, and ...

Three noncoherent minimum mean-squared error (MMSE)-based multiuser receivers are proposed for multipulse modulation. These receivers have a common MMSE prefilter and are followed by one of three phase-independent decision rules. The simplest decision rule selects the maximum magnitude of the MMSE filter outputs, and the other two account for the second-order statistics of the residual multiple...

Noncoherent minimum mean-squared error (MMSE)-based multiuser receivers are proposed for nonorthogonal multipulse modulation. The three proposed receivers have a common MMSE pre-filter and are followed by one of three distinct noncoherent decision rules. The simplest decision rule selects the maximum magnitude of the MMSE filter outputs and the other two decision rules account for the second-or...

The Montreal Cognitive Assessment (MoCA) is a relatively newly designed test that was developed as a tool to screen patients with mild cognitive problems that are not typically detected by the Mini-Mental State Exam (MMSE). While early research suggests that the MoCA is more sensitive to subtle cognitive impairment than the MMSE, there is concern about potential decreased specificity when using...

In this paper, we propose a joint transmit and receive linear filtering based on minimum mean square error criterion (joint Tx/Rx MMSE filtering) for single-carrier (SC) multiple-input multiple-output (MIMO) transmission. Joint Tx/Rx MMSE filtering transforms the MIMO channel to the orthogonal eigenmodes to avoid the inter-antenna interference (IAI) and performs MMSE based transmit power alloca...

conclusions in our population of elderly individuals in northern iran, h. pylori infection was not associated with cognitive impairment in this large population. results the study was performed on 1514 individuals with an average age of 69.3 ± 7.4 years. overall, 836 (55.2 %) of the participants were male. furthermore, 68.7% of the participants had normal mmse score and 75.7% were seropositive ...

b a c k ground: several studies have indicated that executive dysfunction is the main neuropsychological feature of parkinson’s disease (pd). the frontal assessment battery (fab) is a short tool for the assessment of executive functions. p u r p o s e : the aim of this study was to determine the relationship between persian version of fab scores and age, education, mini-mental state examination...

A well–known receiver strategy for a linearly modulated signal transmitted over a frequency–selective channel is channel equalization. Recently it was proposed to employ a minimum mean–squared error (MMSE) channel equalizer for the downlink of CDMA. In this paper, we introduce a new receiver concept using MMSE channel equalization as a first stage and MMSE decision–feedback equalization (DFE) u...

This technical note compares performance of the correlations subtraction architecture of the multistage Wiener filter (CSA-MWF) in the Fractional Fourier Transform (FrFT) domain, MMSE-MWF-FrFT, to the minimum mean-square error, MMSE-FrFT, algorithm and to the conventional MMSE-FFT algorithm in severe cochannel interference. Using four equal power binary phase shift keying (BPSK) signals and a s...

In this paper, a novel robust noncoherent receiver for MMSE interference suppression for DS–CDMA is proposed. The receiver consists of an MMSE filter and a decision–feedback differential detector (DF–DD). The performance of the proposed scheme is investigated analytically and by computer simulations. It is shown that the loss compared to coherent MMSE interference suppression is limited and can...
