|
||||
For quick reference, here's a short list of features and capabilities
|
||||

|
||||
|
||||
- New modes: *FT8* and *FreqCal*
|
||||
|
||||
- Improved decoding performance for JT65, QRA64, and MSK144
|
||||
|
||||
- *SWL* option for third-party decoding short-format MSK144 messages
|
||||
|
||||
- Experimental amplitude and phase equalization for MSK144
|
||||
|
||||
- Options to minimize screen space used by the *Main* and *Wide Graph*
|
||||
windows
|
||||
|
||||
- New set of suggested default frequencies specific to the three IARU
|
||||
Regions.
|
||||
|
||||
- Enhanced scheme for managing table of default operating frequencies
|
||||
|
||||
- Improved CAT control for many rigs, including those controlled
|
||||
through Commander or OmniRig.
|
||||
|
||||
- Bug fixes and tweaks to the user interface

</HEAD><BODY>

|

<H1> Installing the LDPC Software </H1>
|
||||
|
||||
The LDPC software is written in C, and may well work with any C
|
||||
compiler, though it has been tested only with gcc, in Unix and Linux
|
||||
environments, and in the <A HREF="http://www.cygwin.com">Cygwin</A>
|
||||
Unix-like environment that runs under Microsoft Windows. The
|
||||
installation instructions below assume that you are using a Unix-like
|
||||
system.
|
||||
|
||||
<P>All the software, including the documentation you are viewing here,
|
||||
is contained in a tar file, which you can download by clicking one
|
||||
of the options below:
|
||||
<BLOCKQUOTE>
|
||||
<A HREF="http://www.cs.utoronto.ca/~radford/ftp/LDPC-yyyy-mm-dd/LDPC-yyyy-mm-dd.tar">Tar
|
||||
file of LDPC software</A> (0.9 Megabytes)<BR>
|
||||
<A HREF="http://www.cs.utoronto.ca/~radford/ftp/LDPC-yyyy-mm-dd/LDPC-yyyy-mm-dd.tar.gz">Gzipped
|
||||
tar file of LDPC software</A> (0.4 Megabytes)
|
||||
</BLOCKQUOTE>
|
||||
|
||||
<P>Once you obtain the tar file (and uncompress it with gunzip if
|
||||
necessary), you should extract the files with the following Unix command:
|
||||
<BLOCKQUOTE><PRE>
|
||||
tar xf LDPC-yyyy-mm-dd.tar
|
||||
</PRE></BLOCKQUOTE>
|
||||
This will create a source directory called <TT>LDPC-yyyy-mm-dd</TT>, and place
|
||||
all the source, documentation, and other files in this directory.
|
||||
|
||||
<P>If you prefer for this directory to be called something else,
|
||||
rename it <B>now</B>, before compiling the programs, since the file
|
||||
<TT>randfile</TT> in this directory, containing natural random numbers,
|
||||
is accessed according to its path when the programs were compiled.
|
||||
|
||||
<P>Once the tar command above has finished, you should change into the
|
||||
newly-created directory, and type
|
||||
<BLOCKQUOTE><PRE>
|
||||
make
|
||||
</PRE></BLOCKQUOTE>
|
||||
If all goes well, this should compile all the programs (except for some
|
||||
test programs, which can be compiled with <TT>make test</TT>). You
|
||||
may want to edit the file <TT>Makefile</TT> before running <TT>make</TT>
|
||||
in order to change compilation options, such as the optimization level.
|
||||
|
||||
<P>You can run the programs from this source directory, or you can copy
|
||||
them to some other directory by running the <TT>LDPC-install</TT>
|
||||
shell file. For instance, to install them in a bin directory in your
|
||||
home directory, do the following:
|
||||
<BLOCKQUOTE><PRE>
|
||||
./LDPC-install $HOME/bin
|
||||
</PRE></BLOCKQUOTE>
|
||||
|
||||
<P>The source directory contains a copy of all the HTML files
|
||||
documenting the software, such as the one you are reading now, with
|
||||
the file <TT>index.html</TT> being the starting point. It is best to
|
||||
use this local copy when referring to the documentation, rather than
|
||||
get it off the web, since that is faster and also insures that the
|
||||
documentation is for the version that you are using. Just tell your
|
||||
browser to open the URL
|
||||
<BLOCKQUOTE><PRE>
|
||||
file:<I>path-to-software</I>/index.html
|
||||
</PRE></BLOCKQUOTE>
|
||||
where <TT><I>path-to-software</I></TT> is the full path (starting with "/")
|
||||
to the directory where you've put the software.
|
||||
|
||||
<P>The command
|
||||
<BLOCKQUOTE><PRE>
|
||||
make clean
|
||||
</PRE></BLOCKQUOTE>
|
||||
will remove all the compiled programs, as well as the files created when
|
||||
the <A HREF="examples.html">examples</A> are run, and <TT>core</TT>, if it
|
||||
exists.
