A noncoherent receiver for the general case of M -ary partial response multi-h continuous phase modulation (CPM) is presented. The receiver operates on the principle of sequence estimation via the Viterbi Algorithm (VA). It offers a significant complexity reduction from the optimal coherent maximum likelihood sequence estimating (MLSE) receiver. The performance of the receiver is evaluated with...

Background: Accurate and rapid assessment of allograft function is essential in renal transplant recipients in order to detect allograft rejection and to monitor drug nephrotoxicity. We aimed to evaluate the usefulness of cystatin C as a marker of kidney allograft function in the early post-transplant period and to compare this value with that of conventional serum creatinine concentration. Met...

A subliminal channel is a covert communication chsnnel to send a message to an authorised receiver; this message cannot be discovered by any unauthorised receiver. There are some applications that can take advantage of this by hiding secr1:t messages in this subliminal channel. For example, a credit card provider can hide the card holder’s credit history and credit limit in a digital signature ...

As the distribution of the multiuser interference plus noise in time-hopping ultrawide bandwidth (TH-UWB) systems can not be reliably approximated by Gaussian probability density function (PDF), the bit error rate (BER) performance of the conventional matched filter receiver in TH-UWB multiuser systems degrades. In this paper we study a novel TH-UWB receiver based on two PDFs approximating the ...

<p>Currently, breast cancer is one of the most common cancers and a main reason women death worldwide particularly in<strong> </strong>developing countries such as Iraq. our work aims to predict type tumor whether benign or malignant through models that were built using logistic regression neural networks we hope it will help doctors in detecting tumor. Four set binary two dif...

Protein-protein interactions (PPIs) govern basic cellular processes through signal transduction and complex formation. The diversity of those processes gives rise to a remarkable diversity of interactions types, ranging from transient phosphorylation interactions to stable covalent bonding. Despite our increasing knowledge on PPIs in humans and other species, their types remain relatively unexp...

Absfracf This paper considers Multi-Carrier CDMA (MCCDMA) communication systems. Recently, the asymptotic performance of a multiuser MMSE receiver for a MC-CDMA system has been established, assuming orthogonal spreading codes and equal powers. A similar study has also been conducted for a DS-CDMA system, considering in this ease unequal powers. The introduction of orthogonal codes can he consid...

Methods The study was completed as a prospective observational cohort study at a regional teaching hospital. The discriminatory power (ability to discriminate between survivors and non-survivors) of the models was estimated using the area under the receiver-operating characteristics curve (AUROC). Values above 0.8 represent good discriminatory power. Calibration (accuracy of the prediction) was...

Differences in quality performance score had been reported for the routinely used diagnostic methods for malaria at different settings. There is therefore a need to evaluate the test performance of the routine diagnostic methods for malaria detection in Ho, a setting with no recorded quality evaluation on malaria diagnosis. The hospital-based cross-sectional study was conducted comprising 299 o...
