This paper presents issues to be considered when designing multi-carrier WCDMA basestations. Two topics will be the main focus of this discussion; the power amplifier linearization and the peak-to-average power reduction of a multi-carrier WCDMA signal, both of which are important for efficient operation of wideband power amplifiers and cost-effective design of the overall base station. WCDMA signal characterization, technology selection, linearization, and peak reduction methods are discussed. | PMC PMC-SIERRA Multi-Carrier WCDMA Basestation Design Considerations -Amplifier Linearization and Crest Factor Control Technology White Paper Andrew Wright Director Product Research Oliver Nesper DSP Design Engineer Issue 1 August 2002 PMC-2021396 2002 PMC-Sierra Inc.
