<pre wrap="">***** High Performance Software Defined Radio Discussion List *****
Current SDRs use the software equivalent of zero IF techniques, i.e. DDC,
in order to provide (multiple) receivers. Whist this is quite effective,
much of the initial DSP work is done using FPGAs, or a combination of FPGA
plus dedicated DSP chips and microprocessors, rather than totally within
the PC.
As more complex features are added, the size and complexity of the FPGA
and DSP code increases. The skills to write, debug and maintain this code
is only available via a small percentage of software engineers, or
enthusiasts, in comparison to those able to write code for PC based
hardware.

Hi,<br>
<br>
I'm just a "end-user" and not a software engineer, so it's not very
easy, for me, to understand all of this.<br>
Does it mean that that this "new board" is connected between your
sdr transceiver (hermes etc) and your PC?.<br>
I would rater like a 'stand-alone' and 'High Performance' solution
for better DSP functionality etc, <br>
and to get rid of my pc, then an extra board that just needs more
soft- and firmware....<br>
But I understand that this is very exiting for software engineers,
so good luck.<br>
