DIGITAL PREDISTORTION APPARATUS AND METHOD FOR IMPROVING PERFORMANCE USING PEAK LEVEL EXPANSION |
摘要 |
A method an apparatus improve linearization performance and reduce a convergence time of a Digital Pre-Distorter of a power amplifier. An input signal is received. A peak level of the input signal is expanded based on an expansion threshold. And the expanded peak level of the input signal is linearized through Digital Pre-Distorter (DPD) training on the expanded input signal. |
