We would like to know how to optimally use an PA with the AD9361 part for non-constant envelope modulations.
For that we're thinking about TX linearization.
We want to somehow sample the TX signal from the PA output back and use that info.
So there are 3 questions:
- How (where in the device) to sample the TX signal?
- What mode to use for this optimization (using the max power output without distortion)?
- Are there some pre-distortion algorithms to use?
