[Discuss-gnuradio] DPSK2 Demodulator

[Ralf]

Hi,

we are trying to use DPSK2 modulator and demodulator during our first 
trials.
As far as we can see there is hardly any documentation available on this.

We would appreciate a few explaining words from somebody who knows how to
configure the demodulator so that data is correctly received.
What synchronization method(s) is/are included?
Raised-cosine-filter for matched filtering seems to be included?

We tried like this with no success:
Modulator:
Type: DQPSK
Sample/Symbol: 2
Excess BW: 0.35
GrayCode: YES
Verbose: OFF
Logging: OFF

Demodulator:
Sample/Symbol: 2
Excess BW: 0.35
FLL Alpha: 0.01
Phase Alpha: 0.1
Timing Max Dev: 1.5
Omega Relative Limit: 0.005
GrayCode: YES
Verbose: OFF
Logging: OFF
Sync Out: ON

Thanks in advance!
Ralf
