Re: [Discuss-gnuradio] Continous PSK/ FSK transmitter with discrete data

Sure, but it is an example of doing it in software with minimal latency.
You could do the same with HDLC Flags for idle symbols. That's quite common.

I am aware of your example, you use ccsds idle frame insert as a mechanism
to achieve continous modulation. However, that is a pretty specific
implementation.

I've got a pretty complicated example at
https://github.com/dcajacob/gr-ccsds However, it could be simplified by
removing the convolutional encoding.

[Discuss-gnuradio] Continous PSK/ FSK transmitter with discrete data

2018-03-12 Thread Mehmet Ozcelebi 
 Dear All,
 I have been playing with the blocks shown in " Guided Tutorial PSK
Demodulation" and want to
implement my own Transmitter/ Receiver pair.
 First I tried to replace the "Random Source" or "File Source" blocks with
a "Socket PDU-TCP Server". I observed that modulation happens only when I
sent some characters and of course the demodulator could not lock properly
and the data sent is not received correctly.
 What I want is a continous transmission (no burst solutions please). Maybe
something where the flowgraph generates "0" s if there is no data from the
"Socket PDU" and enters a scrambler.
 Which blocks should I use.
 Thank you in advance.
