  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. 3 a novel recursive least - square ( rls ) blind space - time receiver algorithm based on the constrained condition, which can completely avoid the matrix inversion introduced into by constraints ( comparing with the normal rls ), is proposed for multi - path slow fading cdma channels. the computational complexity of this method is not only lower than that of the normal rls, but also lower than that of both lms and ls blind space - time receiver methods that are realized based on the rosen ' s gradient projection. and the speed of convergence of the presented rls blind space - time receiver algorithm is better than that of both lms and ls blind space - time receiver methods

    3 、針對多徑慢衰落通道下ds - cdma盲空時接收機中線性約束二次規劃問題提出一種新的遞歸最小二乘演算法，該演算法完全避免因約束而引進的矩陣求逆運算（相對于常規的遞歸最小二乘演算法） ，不但運算量比常規的要低，而且比基於rosen梯度投影實現的最小均方（ lms ）與最小二乘盲空時接收機演算法還低，且收斂速度比基於rosen梯度投影實現的最小均方（ lms ）與最小二乘盲空時多用戶檢測都好，將提出的新的遞歸最小二乘演算法與提出的數據選擇方案結合起來可以進一步降低其運算量，具有很大的實用價值，最後通過模擬實驗進一步分析了其性能。
  5. It simulates the incoming waves to the thinned antenna array corresponding to any image scene to be measured
