在本篇論文我們提供一個結合多載波分碼多重進階系統和多級威能濾波器的方法,在假設載波頻率為已知的情況下,設計其接收端。在之後的章節會有這兩種理論的介紹,也有其特性的分析。緊接之後為本篇論文所使用的方法介紹。從本論文的模擬結果可發現,本論文所提供的方法比使用威能濾波器以及逼零演算法的系統有更低的誤差。此外,我們將接收端延伸到多根天線的系統,接著討論及比較其模擬結果。 In this thesis, we provide a method which combines multicarrier code division multiple access with multistage Wiener filter to design the receiver with the assumption of perfect synchronization of the carrier frequency. The introduction and features of them are presented later, and so are the manners which we supply. The outcomes of the simulations show that this method provides better performance than the system with Wiener filter or zero-forcing. Further, we extend this structure to multi-antenna for receiver, and the results are discussed according to the comparison of simulations.
