ESTIMATING POWER AMPLIFIER NON-LINEARITY IN ACCORDANCE WITH MEMORY DEPTH |
摘要 |
<p>Reducing a non-linearity effect of a power amplifier includes receiving signals at off-line inverse and forward models. The signals include an input signal, a pre-distorted signal, and an output signal. The output signal exhibits distortion with respect to the input signal, where the distortion includes an impairment effect and a non-linearity effect. The impairment effect is reduced in accordance with the signals. A memory depth of the power amplifier is estimated in accordance with the signals to generate memory information. Non-linearity of the power amplifier is estimated in accordance with the memory information. Pre-distortion information is calculated according to the estimated non-linearity. The non-linearity effect is reduced using the pre-distortion information.</p> |
