Use the etoolbox package and its \patchcmd macro to selectively change sig-alternate' s definition of \maketitle, i.e. remove the \@copyrightspace macro (which is responsible for the copyright space).
\documentclass{sig-alternate}
\usepackage[english]{babel}
\usepackage{blindtext}
\usepackage{etoolbox}
\makeatletter
\patchcmd{\maketitle}{\@copyrightspace}{}{}{}
\makeatother
\begin{document}
\author{lockstep}
\title{How to remove the copyright space}
\maketitle
\blinddocument
\end{document}
(The blindtext package is only used to add some dummy text to the example.)
If the organizers of an IEEE sponsored conference want headers like this for their conference papers, they must have their own way to include them that is compatible with the IEEEtran class. I can't imagine they have suggested using the fancyhdr package, which conflicts with IEEEtran. @Werner's solution works but effectively overrides IEEEtran headers.
The conference option of IEEEtran removes running headers from your paper.
This was their choice, I guess, and normally that should be respected --- they're the publishers and they should get what they want (or they should make sure that they implement what they want in the IEEEtran class that they provide).
If you have to use the conferece option and you absolutely want to have a running header, both in the first page and in all other pages, then I suggest that you get rid of the fancyhdr package and that you add something like the following to your preamble:
\makeatletter
\let\old@ps@headings\ps@headings
\let\old@ps@IEEEtitlepagestyle\ps@IEEEtitlepagestyle
\def\confheader#1{%
% for all pages except the first
\def\ps@headings{%
\old@ps@headings%
\def\@oddhead{\strut\hfill#1\hfill\strut}%
\def\@evenhead{\strut\hfill#1\hfill\strut}%
}%
% for the first page
\def\ps@IEEEtitlepagestyle{%
\old@ps@IEEEtitlepagestyle%
\def\@oddhead{\strut\hfill#1\hfill\strut}%
\def\@evenhead{\strut\hfill#1\hfill\strut}%
}%
\ps@headings%
}
\makeatother
\confheader{%
12$^{th}$ Iranian Conference on Intelligence Systems,
4-6 February 2014, Bam, Iran
}
Also, I suggest that you end your lines with % in your \IEEEpubid, unless you want the copyright notice not to be right-aligned properly with the left column.
\IEEEpubid{%
\makebox[\columnwidth][l]%
{\hfill%
978-1-4799-1228-5/13/\$31.00~\copyright~2013 IEEE%
}%
\hspace{\columnsep}%
\makebox[\columnwidth]{}%
}
Best Answer
In section IV.D of the
IEEEtranmanual you can find the details on how to use\IEEEpubid. IV.C explains\markbothfor running headers.The
conferenceclass option disables both though.A fix for
\markbothis to issuein your preamble. You can change the contents of the first
hboxto suit your needs.If you are not using the
conferenceoption you can doAs documented in the manual, the
conferenceclass option disables both\markbothand\IEEEpubid.
