Can you please provide a reference to Phil's document - Other than
this email and Phil's response I can't find anything under this
subject.<br>
<br>
Thanks,<br>

font-family:Arial">Nice write-up Phil. Thanks for sharing
your thoughts on a
future path of SDR development. In your text, I read SDR
as primarily "software
defined receiver". I would like to see a broader "software
defined
radio", to include expansion capabilities in the front end
hardware,
including TX. In my mind, this should include not only the
ability to add
multiple ADCs for receive, but also multiple DACs for
transmit. This would open
the possibility (for example) for both transmit and
receive "beam
steering" using software determined phasing of a vertical
antenna array
for both transmit and receive. Other applications would
also be possible with
multiple independent transmit and receive hardware paths.<o:p></o:p></span></font></p>

this, now that the
available hardware (ADC, DAC, data transfer and processing
power) capabilities are
all catching up with the dreams!<o:p></o:p></span></font></p>
