Adaptive predistortion technique for linearizing a power amplifier for digital data systems |
摘要 |
Distortion introduced into a multiamplitude signal format by a high power microwave amplifier is compensated by a system which adapts itself to non-linearities present in the amplifier and predistorts the input signals before they are subjected to the non-linearities created by the amplifier. The degree of predistortion is non-fixed and varies or is updated as the non-linear conversion characteristics of the amplifier change with time.
