@@ -8,11 +8,13 @@ This folder contains work in progress for digital predistortion. 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.
