In a two-user scenario, the closed-form ergodic capacity of bi-directional cooperative NOMA is derived and it is proven to be better than those of other techniques. Based on the ergodic capacity, the algorithms to find optimal power allocations maximizing user fairness and sum-rate are ...
The framework and experiment design of this study is shown in Fig.1and described in detail in the following sections. The main objective is to compare the performance of different HDAs across different input datasets. On the basis of the review of research literature on HDAs, we have selected...
Partial CSIT is a more realistic assumption. In particular, each transmitter can acquire the CSIT of its local reverse link (from the receiver) using channel estimation. With time division duplex (TDD) and based on channel reciprocity, such CSIT can also be used for the local forward link [1...
Base station cooperation is an attractive technique to increase the spectral efficiency of multi-cell systems. One of the challenges in multi-cell systems is obtaining accurate channel state information (CSI) at the base station. One source of CSI inaccu
Reports testingreports are another form of questions, conceivably with higher visibility and wider audience. Privacy terms that characterize ‘purpose’ are fundamental to check that sensitive data is not reported with the exception of specified uses. ...

The rest of this paper is organized as follows. In Section 2, system model is introduced. The closed-form expressions of system throughput for the system with the direct link and without direct link are derived in Section 3. The optimal power splitting factor for the system without direct lin...
The impact of multi-antennas cognitive relay for an FD NOMA system with non-linear EH was investigated in [26]. Minimizing the transmit power requirement for full and partial CSIT of FD SWIPT NOMA systems was investigated in [27]. Unlike the works of [24,25,26,27], Agrawal et al. ...
The approach of analyzing the behavior of emotions, opinions, and feelings for a specific entity or subject that is expressed in the form of text is known as opinion mining or sentiment analysis. The accomplishment of sentiment analysis can be achieved at the word, phrase, sentence & document ...
The prospect of a paraphyletic Aciliini with Eretini nested inside was quite surprising, but tantalizingly suggests the possibility that the enigmatic Tikoloshanes eretiformis is, indeed, closely related to Eretini. A dated phylogenetic hypothesis with robust support is needed in order to test ...
