Submit a manuscript through EDAS and I am using the IEEEtran class (conference option). EDAS gives the following errors:

Solutions:

1. May be caused by figures or tables which cross two columns.

Before modification:

1. begin{figure*}[ht]

4. caption{Schematic diagram of the hybrid precoding system under consideration}label{fig:BlockDiagram}
5. end{center}
6. end{figure*}

After modification：

1. begin{figure*}[htpb]
2. centering
3. begin{minipage}[t]{0.7linewidth}
4. includegraphics[width= 5.6in,height=3in]{Figure/SystemSchematic_new.eps}
5. caption{Schematic diagram of the hybrid precoding system under consideration}label{fig:BlockDiagram}
6. parbox{ 6.5cm}{small hspace{1.5cm} }
7. end{minipage}
