This paper analyzes the influence of the delay estimation error on the performance of the predistorter. The evaluation criteria are the adjacent channel power ratio ( ACPR ) and the normalized mean square error ( NMSE ).
Analysis of Influence of Low Frequency Factor to Adjacent Channel Power(ACP) Leakage of Power Amplifier Used for W-CDMA Handset
This technique can efficaciously correct for both amplitude and phase distortion of power amplifiers. 2. Individually controlled by look-up table and adjacent channel power minimization, two kinds of adaptive predistortion linearizer are formed and simulated with computer.
The modeling performance is assessed in terms of in-band and out-of band errors, such as normalized mean square error and adjacent channel error power ratio, and it is compared with a conventional NARMA, a memory polynomial with respect to accuracy and computation complexities.
For implement of wide band modulation, multi-carries and elimination of adjacent channel interference to satisfy BER requirement in WCDMA system, which is most popular in 3G technology, the linearity requirement of the base station power amplifier becomes tighter. index;
