摘要：
A method and power amplification system for achieving digital pre-distortion of wideband, power amplifiers with reduced observation bandwidth are disclosed. A digital pre-distorter system uses a reduced transmitter observation receiver bandwidth combined with a high transmit path sampling rate to linearize a power amplifier across a broad spectrum that may extend to beyond about five times a bandwidth of a signal input to the system.
