Abstract
The predistortion is described firstly, then a summary of clipping technology is followed, the analysis of clipping´s influence on predistortion is provided lastly in this paper. Through analysis and simulation, following ideas are pointed out: As for TWTA power amplifier model, clipping cannot improve the predistortion performance, while too large clipping will influence predistortion effect. In view of memory polynomial model, clipping could not improve predistortion performance at large, but proper clipping can get little improvement of predistortion performance.
