In the 1-st part, digital predistortion method for the M-CCDMA transmitter PA is investigated; in the 2-nd part, fully digital I-Fbaseband converter circuit for the M-CCDMA receiver is investigated. In both topics, theoretical design and hardware implementation have been taken into consideration.application/pdf1201131 bytesapplication/pdfzh-TW國立臺灣大學電信工程學研究所功率放大器非線性數位中頻處理器多載波調變Power AmplifiersNonlinearitiesPredistortionProgrammable IF ProcessorOFDMMulticarrier Modulationreporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/20270/1/912219E002024.pdf
