傳統的通道估計演算法需要訓練序列使接收端的參數調整到理想狀態，而本文提出的基於ica的通道估計的多用戶檢測演算法不需要訓練序列，它是利用下行通道的固有特點，用ica的盲源分離法估計出多徑通道的卷積矩陣，從而從中提取出通道的延遲信息，模擬實驗結果證明這種方法在節省了頻譜資源的同時取得較好的估計效果，使得傳統的接收機的誤碼性能得到了很大的提高。In order to solve those problems, this thesis is based on a case study of the 2002 senior high school entrance exam in huangzhou district, huanggang city, hubei province. by applying the principles of language testing and using the computer - aided analysis of the test, it gives a detailed analysis and evaluation of the test along the criteria of language testing and the english curricular criteria for full - time compulsory education common middle school
