  1. But the frequent use of training sequence is certainly a waste of channel bandwidth. research shows that with the prior knowledge of only the signature waveform and timing of the user of interest, blind adaptive multiuser detector can effectively detect data symbol of the desired user without training data sequence for every active user

    在傳統多用戶檢測技術基礎上，自適應多用戶檢測利用訓練序列在僅知道期望用戶地址pn碼及其定時信息條件下就可以進行檢測，不足的就是訓練序列佔用了額外的頻率資源。
  2. Periodic training sequence is essential for the conventional adaptive equalizers to combat the isi, but it wastes plenty of bandwidth

    採用傳統的自適應均衡技術抑制碼間干擾，需要重復發送訓練序列，佔用大量本不富裕的帶寬。
  3. 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。
  4. Training sequence code

    訓練序列碼
  5. In time synchronization, we got better performance by the controlling of the polarity of training sequences using pn code

    時間同步方面，通過pn碼控制訓練序列極性，達到更好時間同步效果。
  6. In order to reducing isi recovering transmitted signal equalizer have to be used in the reciever. because blind channel equalizer can reduce the intersymbol interference without the assistance of the transmitted sequence, it has been becoming a very popular research topic in recent years

    盲均衡器由於不需要訓練序列，僅利用接收信號的統計特性就能對通道特性進行均衡，消除碼間串擾，成為近年來通信領域研究的熱點課題。
