| dc.description.abstract | 本篇論文主要研究為單載波傳輸以及空間分割多重存取技術，其利用多根天線的接收與傳送多個不同訊號，使不同的訊號可以在同時間與同頻帶下傳送。利用上述技術，我們希望簡化使用者的傳送或接收端的架構，盡量將通道補償的工作由基地台完成，並且分別討論上行與下行模式：
上行模式，接收端為基地台。我們考慮在超高速移動的環境中，訊號接收後先經過空間分割多重存取偵測器。再利用此偵測結果經過並排干擾消除與等化器。我們提出不同組合的疊代方式，以及頻率域和時間域等化器的比較。 下行模式，傳送端則為基地台。我們使用預先等化器於傳送端，但是需要已知通道資訊。在高速移動的環境中估測通道資訊容易有錯誤，我們提出使用者利用等化器消除訊號的干擾。 | zh_TW |
| dc.description.abstract | This thesis emphasizes on single-carrier transmission and SDMA techniques, which can receive and transmit different signals at the same time and on the same frequency band by using multiple antennas. Exploiting the above techniques, we hope to simplify user’s structure of transmitter or receiver by letting the base station deal with the compensation of channel as far as possible. Then we discuss the uplink and downlink modules.
On the uplink module, receiver is the base station. We consider in very high mobility environment, the signals pass through the SDMA detector after it is received. Then PIC and equalizer use the result of detection. We propose different combinations of the iterative method, and the comparison of frequency domain and time domain equalizer. On the downlink module, the base station is transmitter instead. We utilize pre-equalization for the transmitter. It may have the imperfect information when estimates channel in very high mobility environment. Therefore, we propose that user uses the equalizer for eliminating the interference of signal. | en |
