We a framework for the design of low-complexity and high-performance receivers multidimensional overloaded non-orthogonal multiple access (NOMA) systems. The is built upon novel compressed sensing (CS) regularized maximum likelihood (ML) formulation discrete-input detection problem, in which l <sub ...

In this paper, we consider a single-server queue fed by K independent renewal arrival streams, each representing a different job class. Jobs are processed in a FIFO fashion, regardless of class. The total amount of work arriving to the system exceeds the server’s capacity. That is, the nominal traffic intensity of the system is assumed to be greater than one. Jobs arriving to the system grow im...

We consider the problem of designing a low-complexity decoder for antipodal uniquely decodable (UD) /errorless code sets overloaded synchronous code-division multiple access (CDMA) systems, where number signals Kamax is largest known given length L. In our complexity analysis, we illustrate that compared to maximum-likelihood (ML) decoder, which has an exponential computational even moderate le...

Here, overloaded concentration profiles were predicted in supercritical fluid chromatography using a combined two-dimensional heat and mass transfer model. The balance equation provided the temperature pressure inside column. From this density, viscosity, mobile phase velocity column calculated. adsorption model is here expressed as function of density phase. system consisted Kromasil Diol pack...
