We're writing a gmsk radio module with low bitrate (<5 kbps) and continuous constant bitrate transmission using Gnuradio 3.0.3 and USRP. The code is based on the digital/tx_voice.py example, and I have two unanswered questions.
By hacking on the example, pick_bitrate fails to return a lower bitrate than 35.714kb/sec. Is it possible to support a precisely defined lower bitrate, or is there a technical limitation? Another issue is underflow handling. Is there a way to gracefully detect and handle underflow if the producer (codec) lacks behind or stops? If unhandled, we would loose syncronization with the receiver. -- Håvard Espeland _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
