[Discuss-gnuradio] Determining distance from OFDM signals

2019-06-05 Thread Andrew Wolfram
Hi, I'm trying to alter the file ofdm_txrx.py ( https://github.com/gnuradio/gnuradio/blob/master/gr-digital/python/digital/ofdm_txrx.py) to get phase information from the carrier data so I can calculate an approximate distance between two USRP devices. Ideally I want to grab data from one of the

[Discuss-gnuradio] Basic duplex communication using TDD

2019-04-18 Thread Andrew Wolfram
Hi, I'm attempting to demonstrate very, very basic duplex communication between two USRP N210s via time division duplexing. Essentially, I want to have one USRP receiving first, and the other transmitting first. When the receiving USRP detects the end of the message, it starts transmitting its
