摘要: Disclosed are implementations that include a method comprising applying at least one input signal to power amplification system, includes transmit chain with amplifier (PA) producing output non-linear distortions, produce signal, and measuring observed of the using an observation receiver coupled chain, having receive bandwidth smaller than chain. Measuring multiple frequency segments signal. The further determining or more sets digital predistortion coefficients based on measured each being associated respective set operating conditions system.
