Low latency, high data speeds, and a higher degree of perceived service quality for consumers base station capacity are only some the advantages fifth generation (5G) mobile communications. This paper focuses on design precoding system downlink transmission multi-user multiple-input multiple-output (MU-MIMO). For MU-MIMO systems, traditional techniques investigated difficult since transmitter m...

We consider a recent method for generating an input signal with a desired auto correlation while satisfying both input and output constraints for the system it is to be applied to. This is an important problem in system identification, since the properties of the identified model depend on the used excitation signal while on real processes, due to actuator saturation and safety considerations, ...

In this paper, we propose a novel method using multiple-objective programming problems to answer the following question: if among a group of decision making units (DMUs), a subset of DMUs are required to merge and form a new DMU with specific input/output levels and a predefined efficiency target, how much should be the outputs/inputs of the merged DMU? This question answered according to the c...

In this article, a special type of orthogonalization is obtained to construct a multiple input transfer function model. By using this technique, construction of a transfer function model is divided to sequential construction of transfer function models with less input time series. Furthermore, based on real and simulated time series we provide an instruction to adequately perform the stages of ...
