The present invention relates to a method of influencing an input signal (x), in particular an input signal of a power amplifier of a wireless communication system, wherein said input signal (x) has a range of input amplitudes (r, . . . , r), wherein a correction signal (&#x393;(x)) depending on said input signal (x) is generated, and wherein said input signal (x) is influenced depending on said correction signal (&#x393;(x)). A generation of said correction signal (&#x393;(x)) is based on a plurality of base functions (&#x3c6;, &#x3c6;, . . . , &#x3c6;), and said range of input amplitudes (r, . . . , r) is divided into intervals (r,r),(r,r), . . . ,(r,r), wherein each of said base functions (&#x3c6;, &#x3c6;, . . . , &#x3c6;) contributes to said correction signal (&#x393;(x)) in a limited number of intervals ((r,r),(r,r), . . . ,(r,r)). Thus it is possible to change parts of the correction signal by adapting some of said base functions without influencing the whole correction signal.
