The estimation accuracy can be shown to outperform the conventional frequency-domain channel interpolators. Moreover, comparing to time-domain DFT-based channel estimators, the proposed algorithm greatly reduces the hardware complexity. In addition, the architecture modification and IC design of such a MC-CDMA baseband receiver incorporating the proposed WLS estimation for residual synchronization errors as well as the aforementioned channel estimation algorithm has been completedapplication/pdf243267 bytesapplication/pdfzh-TW國立臺灣大學電機工程學系暨研究所多載波碼域多工智慧型 天線通道參數估測基頻接收機內 插器MC-CDMAadaptive arraychannel estimationbaseband receiverinterpolator下世代無線網際網路用的多載波碼域多工收發機之研製— 子計畫三:多載波CDMA 收發機基頻模組之製作(3/3)reporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/8006/1/922219E002012.pdf
