It requires: - A feedback connection from the power amplifier output, at an appropriate power level for the B200. Usually this is done with a directional coupler. - ODR-DabMod with enabled dpd_port, and with a samplerate of 8192000 samples per second. -- Synchronous=1 so that the USRP has the timestamping set properly. +- Synchronous=1 so that the USRP has the timestamping set properly, internal refclk and pps + are sufficient for this example. +- A live mux source with TIST enabled. See dpd/dpd.ini for an example. TODO ---- -Fix timestamps and test if frame data is valid. +Implement a PA model that updates the predistorter. |
