To overcome this problem, we introduce a conceptual approach combining sub-symbolic and symbolic methods for human-centric explanations, that incorporate domain knowledge and causality.  ...  The evaluation with a chemical dataset and ontology shows the explanatory value and reliability of our method.  ...  We aim to develop a hybrid method by combining GNNs, sub-symbolic explainer methods and inductive logic learning.  ...

In this paper, we propose a simplified Maximum Likelihood (ML) detection scheme for Multiple-Input Multiple-Output (MIMO) system that has much less computational complexity than the conventional ML detection  ...  In the first step, several 'candidate symbols' are selected for each sub-stream by linear detection method.  ...  In the second step, N-dimensional symbol combinations for whole sub-streams are chosen based on each candidate symbol. The chosen combinations are called 'candidate symbol combinations.'  ...

Experimental results show that our method can get better results than Thung et al.'s method and Chang et al.'s method.  ...  THE PROPOSED METHOD In this section, we shall present our method with the branch-and-bound strategy [4] .

Analytical modeling for EVM in OFDM transmitters including the effects of IIP3, I/Q imbalance, noise, AM/AM and AM/PM distortion

<span title="">2013</span> <i title="IEEE"> <a target="_blank" rel="noopener" href="https://fatcat.wiki/container/yb4g5d6aszdj7coou6jp5dreee" style="color: black;">2013 18TH IEEE EUROPEAN TEST SYMPOSIUM (ETS)</a> </i> &nbsp;
In this paper, we present a method for accurately calculating the Error Vector Magnitude (EVM) of OFDM transmitters based on their IQ mismatch, IIP3, noise, AM/AM and AM/PM distortion.  ...  This method helps test engineers to compute the EVM based on already measured parameters and eliminates the need to develop and set-up EVM measurements.  ...  Different methods have been used to combine these effects. In [5] , IQ imbalance and non-linearity effects are added vector wise for deterministic movements.  ...
