dc.description.abstract	多輸入多輸出(MIMO)區塊傳輸循環字首(CP)系統已經被證實可以達到高傳輸率，並可以簡化通道偵測和通道等化。為了要展現多輸入多輸出區塊傳輸循環字首系統的好處，我們需要準確的通道狀態資訊。為了使通道估計有更高的頻寬利用率，基於在傳輸端使用預編碼的盲通道偵測方法相較於先前的盲通道偵測方法有更多項的優勢，因而成為近來的研究對象。在這篇論文，我們提出了新一類的預編碼器，當盲通道偵測器使用我們所提出的預編碼器時，相較於使用之前研究所提出的預編碼器，可得到更為精確的通道估計。另外，我們提出一種新的方式，並藉由理論的推導和模擬的測試，發現可以用來做通道估計演算法的分析。我們也介紹了跟通道估計效能很有關聯的四個因素，其中除了雜訊因素之外，其他的因素在之前的研究裡並未被提過。我們還發現若降低這些因素，可得到更好的通道估計效能。藉由模擬，可以看出當通道偵測器採用所提出的預編碼器，相較於通道偵測器採用之前研究中所提出的預編碼器，可以得到更好的通道估計。	zh_TW
