  3. Verdu derives the ideal of multi - user detection in 1986. the multiple access interference, he deemed it has available information in certainly structure. adopted by the mlsd in the theoretical, it has many good abilities, such as its capability close with the single user ' s, near - far resistance, raised the capacity of the system. thereby come to operate the mud ' s research

    1986年， verdu提出了多用戶檢測思想，認為多址干擾是具有一定結構的有效信息，理論上證明了採用最大似然序列（ mlsd ）可以逼近單用戶接收性能，並有效地克服了遠近效應，大大提高了系統容量，從而開始了對多用戶檢測的研究。
  4. 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。
  5. In addition, sometimes it is impossible to transmit training sequence. however blind equalization technique can depend on only the received data sequence to equalize the channels

    而盲均衡技術可以不用藉助訓練序列，僅僅根據接收到的信息序列對通道進行自適應均衡，因而引起廣泛研究。
