Abstract

Some embodiments relate to systems and methods for capacity based DPD optimization. An example method of capacity based DPD optimization includes choosing a DPD adaptation stimulus to facilitate a SNR estimation. The example method also includes initializing DPD coefficients based on setting the DPD coefficients to an initial guess. Additionally, the example method includes estimating the SNR and calculating the cost function based on the estimated SNR; The example method also includes numerically optimizing the DPD coefficients and updating the DPD coefficient set based on the numerical optimization.
