How many tunable parameters in GNU radios?

GNU Radio
1

Hi All:

I have a very general question, does anyone know how many tunable
parameters
(approximately) are there in GNU radio (e.g. USRP1)?

Suppose two radios need to get/set each other’s parameters, in the
conventional approach, they need a fixed protocol, the number of tunable
parameters will effect the design of the protocol. I am using a
different
approach in which the radios use a common language to “talk” to each
other,
therefore, they can use this language to exchange singling messages and
doesn’t need a fixed protocol.

If anyone knows the answer of my question, it would be very helpful for
the
evaluation of my approach!

Thanks very much!

Difficult question, Rachel, because it depends greatly on the
application
you create. If you are just talking about what parameters the USRP has,
that’s a more constrained set of parameters. There, you basically have
frequency, gain, and sample rate.

You could create a flow graph that does more, though, such as
modulation,
equalizer, filtering, or anything else you can put together using
current
(or future) GNU Radio components.
