An iterative block decision feedback equalizer (IB-DFE) for single carrier modulation is proposed. Filtering operations are implemented by discrete Fourier transforms (DFTs) which yield a reduced computationals complexity, for both filter design and signal processing, when compared to existing DFEs. Moreover, the new IB-DFE allows to cancel, besides postcursors, also the precursors of the iters...

We propose a computationally e cient version of the Decision Feedback Equalizer (DFE) and compare its performance with the conventional DFE. The proposed equalizer requires fewer taps than the conventional one. This reduces the computational load proportionally and leads to faster adaptation. Identical performance of the two structures in terms of probability of error is also demonstrated using...

A 24-year-old female driver with a history of substance abuse was pronounced dead following a single car motor vehicle accident. A surviving front seat passenger witnessed the decedent inhaling "Dust Off" cleaner just prior to losing control of the vehicle. The propellant compound used in this product is the halogenated hydrocarbon 1,1-difluoroethane (DFE). Sealed autopsy specimens were examine...

We propose a new design method, called discriminative feature extraction (DFE) for practical modular pattern recognizers. A key concept of DFE is the design of an overall recognizer in a manner consistent with recognition error minimization. The utility of the method is demonstrated in a Japanese vowel recognition task.

In this paper, we have investigated the global dynamics of a discrete-time middle east respiratory syndrome (MERS-Cov) model. The proposed discrete model was analyzed and threshold conditions for attractivity disease-free equilibrium (DFE) endemic are established. We proved that DFE is globally asymptotically stable when R0≤1. Whenever R˜0>1, has unique stable. theoretical results illustrate...

An improved weighted decision-feedback equalizer (IWDFE) is adopted and experimentally demonstrated to mitigate chromatic dispersion (CD) induced power fading for C-band four-level pulse amplitude modulation (PAM-4) system. Based on a compressed sigmoid nonlinear function, the IWDFE superior conventional DFE, rule-1 rule-2 based WDFEs in reducing both error propagation probability percentage of...

We investigated the speciation of Fe and distributions Fe-binding ligands in hydrothermal plumes over high- low-temperature vents diffuse venting fields above Mariana back-arc spreading center. The concentrations ([L]) conditional stability constants (K’FeL) natural ligand pool were measured by a reverse titration-competitive exchange-adsorption cathodic stripping voltammetry (RT-CLE-ACSV). res...

A new theoretical framework is introduced for analyzing the performance of a finite-length minimum-mean-squareerror decision feedback equalizer (MMSE-DFE) in a multi-input multi-output (MIMO) environment. The framework includes transmit and receive diversity systems as special cases and quantifies the diversity performance improvement as a function of the number of transmit/receive antennas and...

Adaptive modulation is applied in conjunction with a decision-feedback equalizer (DFE) in order to mitigate the effects of the slowly varying wide-band multipath Rayleigh fading channel in a noise-limited environment. An upper-bound mean bit-error rate and bits per symbol performance is introduced for this scheme by utilizing the pseudo signal-to-noise ratio at the output of the DFE in order to...
