Re: [Discuss-gnuradio] How to start with stream tags

[Hoang Ngo Khac]

Thank you Mr. Newman,

I've read (1) GNU Radio Manual on stream tags, (2) slides of Tom Rondeau and (3) Block Coding Guide about stream tags in http://gnuradio.org/redmine/projects/gnuradio/wiki/BlocksCodingGuide#Stream-Tags. They are general and I would like to find some specific example. Anyway, I have some questions. 

1. In (3), they give the example codes for reading/writing stream tags. Where should these codes be inserted?

3. sob and eob are inserted to the data frame. Does the USRP Sink remove these redundant data before transmitting?

Best Regards,

Hoang

Dear List,

I want to make time synchronization for implementation of two-way relaying network. Each node contain both RX chain and TX chain but they should not run simultaneously (half-duplex mode). Therefore, the TX chain is on when it is needed to transmit, and off when the transmission is over. I found that stream tags is the key solution to perform that.

My question is, how should I start to learn about stream tags, where can I find tutorial of stream tags?

Thank you so much.

Best Regards,

Hoang
