The use of dual polarization in mobile satellite systems is very promising as a means for increasing the transmission capacity. In this paper we study a system which uses simultaneously two orthogonal polarizations in order to communicate with the users. The application of MIMO signal processing techniques along with Adaptive Coding and Modulation in the forward link can provide remarkable thro...

An orthogonal forward selection (OFS) algorithm based on leave-one-out (LOO) misclassification rate is proposed for the construction of radial basis function (RBF) classifiers with tunable units. Each stage of the construction process determines a RBF unit, namely its centre vector and diagonal covariance matrix as well as weight, by minimising the LOO statistics. This OFS-LOO algorithm is comp...

The two main cooperative protocols in WLANs are the orthogonal and non-orthogonal ones. We consider this two different cooperative protocols with the amplify-andforward (AF) and decode-and-forward (DF) strategies. In each case, we study the information theoretic performance. Simulation results show that the non-orthogonal cooperative protocol achieves an optimal performance than the orthogonal ...

This paper considers resource allocation to achieve max-min fairness in a selection-based orthogonal frequency division multiplexing network wherein source nodes are assisted by fixed decode-and-forward relays. The joint problem of transmission strategy selection, relay assignment, and power allocation is a combinatorial problem with exponential complexity. To develop effective solutions to the...

By removing the orthogonal use of radio-resources, non-orthogonal multiple access (NOMA) has been introduced to improve spectral efficiency fifth generation (5G) and beyond networks. This paper studies system performance in a dual-hop multi-relay NOMA using decode-and-forward (DF) scheme over Nakagami-m fading channels. A group users is considered, i.e. near far which are decided by how strong ...

A new iterative orthogonal least squares forward regression (iOFR) algorithm is proposed to identify nonlinear systems which may not be persistently excited. By slightly revising the classic forward orthogonal regression (OFR) algorithm, the new iterative algorithm provides search solutions on a global solution space. Examples show that the new iterative algorithm is computationally efficient a...

In this paper, we investigate a relaying wireless sensor network (WSN) with the non-orthogonal multiple access (NOMA) and node selection schemes over Rayleigh fading. Precisely, system consists of two clusters, sink node, an amplify-and-forward (AF) relay. These sensors applying NOMA transmit sensing data from clusters via relay to sink. We derived expressions outage probability throughput for ...
