"the" Book

anybody knows why the book named “Software Defined Radio: with GNU Radio
and
USRP” was never actually published ? i couldnt reach the author , the
publisher didnt give any clear answer and apparently folks at ettus do
not
know the reason either . the only thing i know is that the author works
for
Motorola . could that played a role in all this ? just a bunch of honest
questions from a student .

Regards
