[Discuss-gnuradio] Simple digital data transmitter

[David Barton]

Hi,

 

I have set up the following simple digital data transmitter:

 

 

File source -à   throttle    -à    packet encoder --- >  DBPSK modulator -à USRP2     

File size             sample rate       samples/sym - 2        samples/sym – 2           Inter rate 32  

-variable             3.125M             bits/sym - 1              excess BW – 0.35         Freq 400M

                                                     access code – n/a      grey code - yes             Gain 0

                                                     pad for USRP – yes

                                                     payload len – 0

 

 

What is the transmit (over the air) data rate of this line up ?

 

Please explain how the rate is derived.

 

Thanks,

Dave
