Sorry! Below was a typo! Eb should be set to1, I think. Thank you

Thank u George!!!
I know i have to calculate, but how much I set Eb/N0 to? Now i think it should
be set to 1.

Hello, everybody
I am trying to transmit a DQPSK Modulated Sequence into sky through USRP, but
after the symbols whose types are complex go through the pulse shaping filter,
how can we put them onto a carrier, say cos(2*pi*fc*t). Should we multiply the
complex symbols with cos(2*pi*fc*t) or wit
Read not only the document that I sent you, but the document that Brian
sent you too. You can lead a horse to water, but you can't make it drink.
Both docs tell you have to make the calculation.

I meant: i was just simulating a simple communication system
So... if the noise channel is on your laptop, you must have generated
this channel? Is it a simulated channel? Are you specifying the noise
power?
You're not giving us much information.

Jan,
Sorry. I have been out of touch with GNURadio for a while. I am very
happy to hear that you have some data available to test. I would
really appreciate it if you can find time to upload your data

hence 270MB should downloa
Thank you! What i am trying to do is very simple: I don't use USRP, i just used
a vector as a bit source and have it modulated and transmitted through a noise
channel (on my laptop ^.^ ). Now i can set the value of noise's amplitude, but
there seems to be no way to determine the bit energy! How

the first export statement due to the space before the equal sign.

There's a good article (with commentary from Phil Karn as well) located here:

Hello,
I just started with GNU Radio, and I have a problem with the USRP card which is
not find usrp_firmware.ihx both file and usrp_fpga.rbf because they are not
installed on my fedora version.
Can you tell me where I can be found for added
Thanks in advance

Thanks Michael, it worked flawlessly
