PREDISTORTION METHOD USING A POLYNOMIAL EXPRESSION
摘要
PURPOSE: A pre-distortion method based on polynomial expressions is provided to overcome discontinuity appeared at the boundary of regions by extracting the coefficients of the polynomial expressions. CONSTITUTION: Inputting signals which are the targets of pre-distortion are divided into polynomial expression regions(S210). A plurality of coefficient extracting regions are obtained(S220). The coefficient extracting regions correspond to the polynomial expression regions and include overlapped regions and the corresponding polynomial expression regions. Polynomial expression coefficients, which model the non-linear characteristic of the outputting signals, are extracted(S231). The coefficients of the extracted coefficients corresponding to the polynomial regions pre-distort the inputting signals by each polynomial region(S232).
