Abstract (fin):Tässä diplomityössä esitellään ja analysoidaan menetelmiä signaalin huipputehon ja keskimääräisen tehon suhteen pienentämiseksi laajakaistaisessa CDMA tukiaseman lähettimessä.
WCDMA signaalille esitetään matemaattinen malli, ja tähän malliin perustuen johdetaan matemaattinen malli parametreille EVM (Error Vector Magnitude), PCDE.
(Peak Code Domain Error) ja ACLR (Adjacent Channel Leakage power Ratio).
Johdetut mallit testataan simuloimalla.

Esiteltyjä tehonleikkaus menetelmiä testataan simuloimalla käyttäen erilaisia testidatoja ja erilaisia systeemi spesifikaatioita.
Eri menetelmiä vertaillaan käyttäen kriteerinä saavutettua Crest Factorin pienentymistä.
