在多天線正交分頻多工（orthogonal frequency-division multiplexing，OFDM）的系統下，時空區塊編碼（space-time block code，STBC）以及貝爾實驗室垂直式分層時空（vertical Bell laboratories layered space-time，V-BLAST）可以幫助系統得到多樣性或者有效率的提高輸出。然而在時變的通道下，多天線正交分頻多工系統的錯誤率會大幅提升，原因是時變的通道會導致載波互相干擾。另外多天線正交分頻多工的系統加上時空區塊編碼，會額外產生區塊碼之間的干擾。如果採用傳統的方式不做補償，錯誤率表現會很差。這篇論文中，我們運用疊代式的消除干擾方式，並且提出列表消除干擾（List-SIC）跟疊代式的方法做結合，藉此達到低雜度的多天線解碼器。模擬結果顯示，我們提出方法的錯誤率表現可以接近現行最好的方式，但是大幅降低複雜度。

In multiple-input-multiple-output (MIMO) orthogonal frequency-division multiplexing (OFDM)
systems, space-time block codes (STBC) and vertical Bell laboratories layered space-time
(V-BLAST) are popular techniques to get the diversity gains or multiplexing gains. STBCOFDM
system often relies on the assumption of quasistatic channels. For the time-varying
multipath channel, performance degrades seriously due to co-channel interference (CCI) and
inter-carrier interference (ICI). In this thesis, we propose an iterative interference cancellation
architecture to reduce both CCI and ICI jointly. In particular, a list successive interference
cancellation (List-SIC) algorithm is presented to obtain a candidate list to compute soft information
that is used in the CCI cancellation. Furthermore, an ICI cancellation algorithm
that uses prior List-SIC information from the preceding iteration is proposed. On the other
hand, V-BLAST OFDM also suer severe ICI in fast fading channels. Therefore, we generalize
iterative List-SIC to V-BLAST OFDM. The simulation results show that the proposed
scheme achieves near maximum likelihood (ML) error performance with lower complexity
for STBC-OFDM and V-BLAST OFDM in fast fading channels
