The DPD server port can be tested with the *dpd/show_spectrum.py* helper tool, which can also display a constellation diagram. +File format for coefficients +---------------------------- +The coef file contains the polynomial coefficients used in the predistorter. The file format is +very similar to the filtertaps file used in the FIR filter. It is a text-based format that can +easily be inspected and edited in a text editor. + +The first line contains the number of coefficients as an integer. The second and third lines contain +the real, respectively the imaginary parts of the first coefficient. Fourth and fifth lines give the +second coefficient, and so on. The file therefore contains 2xN + 1 lines if it contains N +coefficients. + TODO ---- |
