<TITLE> Support Programs </TITLE>
</HEAD><BODY>
<H1> Support Programs </H1>
The following programs provide support for testing and performance
assessment.
<P><A NAME="rand-src"><HR><B>rand-src</B>: Generate random message bits.
<BLOCKQUOTE><PRE>
rand-src <I>source-file seed n-bits</I>
</PRE></BLOCKQUOTE>
<P>Creates a file of random messages bits called
<TT><I>source-file</I></TT>, which is suitable for testing the
correctness and performance of other programs. The bits in the file
are independent, and are equally likely to be 0 or 1. They are
generated pseudo-randomly based on <TT><I>seed</I></TT>. The actual
random number seed used will be <TT><I>seed</I></TT> times 10 plus 2,
so that the stream of pseudo-random numbers will not be the same as
any that might have been used by another program.
<P>The <TT><I>n-bits</I></TT> argument specifies the number of bits to
produce. It can be a single number, or it can consist of a block size
and a number of blocks, written with <TT>x</TT> separating these
numbers, with no spaces. Each block is written as a single line, with
the bits in the block represented by the characters '0' and '1', with
no intervening spaces. If the bit count is given by a single number,
the block size is assumed to be one.
<P><B>Example:</B> The following command produces a file containing
3 blocks, each consisting of 15 random bits, produced using the pseudo-random
number stream identified by the <TT><I>seed</I></TT> of 17:
<UL><PRE>
<LI>rand-src rsrc 17 15x3
</PRE></UL>
The contents of the file <TT>rsrc</TT> after this command might be something
like the following:
<BLOCKQUOTE><PRE>
111011000110000
010010110010111
100000000000111
</BLOCKQUOTE></PRE>
<P><A NAME="verify"><HR><B>verify</B>: Verify that decoded blocks are
codewords, and that they match the source.
<BLOCKQUOTE><PRE>
verify [ -t ] <I>pchk-file decoded-file</I> [ <I>gen-file</I> [ <I>source-file</I> ] ]
</PRE></BLOCKQUOTE>
<P>Checks whether or not the blocks in <TT><I>decoded-file</I></TT>
are codewords, according to the parity check matrix in
<TT><I>pchk-file</I></TT>. If <TT><I>gen-file</I></TT> is specified,
the message bits of the blocks are also checked against the
corresponding blocks of <TT><I>source-file</I></TT>, or against zero
if <TT><I>source-file</I></TT> is not given. (Normally, one would
leave out <TT><I>source-file</I></TT> only if the <A
HREF="channel.html#transmit"><TT>transmit</TT></A> command was used
with an argument specifying that zeros are to be transmitted, rather
than a file of encoded data.)
<P>A summary of the results is displayed on standard error, giving the
total numbers of blocks, the number with parity check errors, and, if
<TT><I>gen-file</I></TT> was specified, the number of blocks with
source errors and the number with errors of both kinds. If
<TT><I>gen-file</I></TT> was specified, a second
summary line displays the bit error rate from
comparing the decoded message bits with the true message bits (zeros
if no <TT><I>source file</I></TT> was given).
<P>If the <B>-t</B> option is given, block-by-block results are
printed on standard output in two or three columns, giving the block
number (from zero), the number of parity check errors for that block,
and the number of errors in source bits. The last column is omitted
if <TT><I>gen-file</I></TT> is not specified. The columns are
preceded by a line of headers, so the file is suitable for reading
into the S-Plus or R statistics packages, with a command such as
<BLOCKQUOTE><PRE>
data <- read.table(<I>file</I>,header=T)
</PRE></BLOCKQUOTE>
<P>Warning messages are displayed on standard error if the number of
bits in <TT><I>decoded-file</I></TT> is not a multiple of the block
length, or if <TT><I>source-file</I></TT> is too short. Newlines
in these files are ignored, even though they would normally occur
at the ends of blocks.
