It requires: + +- USRP B200. +- Power amplifier. +- 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, internal refclk and pps + are sufficient for this example. +- A live mux source with TIST enabled. + +See dpd/dpd.ini for an example. + +TODO +---- + +Implement a PA model that updates the predistorter. |
