Analytical condition were as follows, column : 10 % modified polyethylene glycol 20m on acid washed 201, 2m column with 3 mm i. d., fid as detector, phe - nylmethyl ketone as internal standard compound
以10 %改性聚乙二醇20m為固定液,苯乙酮為內標物,氫火焰離子化檢測器,內標法定量分析異辛酸。 -
Traditional delay estimation based on ica requires the trail sequences to initialize the receiver, but the new algorithm based on ica does not need the trail sequences. it is based on the channel character of downlink, using the ica algorithm to estimate the multi - path mixture matrix, then, find the delay information which is embodied by the column vector of the mixture matrix. the simulation results show that it does enhance the performance of traditional detector without wasting the invaluable frequency resource
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。 -
