  1. One of which is based on the maximum signal - to - noise ratio ( msnr ) criterion, it can improve the performance of the array system only when the processing gain of the given cdma system is high enough such that the desired signal can become dominant after dispreading. the other is based on the maximum signal - to - interference - plus - noise ratio ( msinr ) criterion, and it has well performance when strong interferers occur

    一種是基於最大信噪比準則的演算法，該演算法適用於cdma系統的處理增益比較大，即解擴以後期望用戶信號遠大於干擾信號的情況；另一種是基於最大信干噪比準則的演算法，該演算法在強干擾存在的情況依然有較好的性能。
  2.

    用譜分析法，把陣元問的互耦用陣列的歸一化阻抗矩陣來描述，推導了均勻線陣的最佳權矢量及信號干擾噪聲比的表達式，模擬計算了互耦對自適應天線陣列的信號干擾噪聲比的影響，給出了一種校正互耦的方法，數值模擬了校正的效果。
  3. Under ideal conditions, adaptive array signal processing methods can get excellent performance and adaptive beamformers provide an improvement in array output signal - to - interference - plus - noise - ratio ( sinr ) in comparison with conventional beamforming. in practical operating circumstances, the performance of adaptive array signal processing methods degrade extremely due to existing errors

    但是，在實際系統中總存在有誤差，包括自適應訓練樣本有限次快拍引起的協方差矩陣的估計誤差和各種系統誤差，誤差使得實際陣列流形與理想陣列流形存在差異，這時自適應陣列信號處理的性能會急劇下降。
  4. The simulation results demonstrate that the algorithm proposed in this paper has better performance with lower mean squared error ( mse ) and higner output signal to interference plus noise ratio ( senr )

    文中的實驗結果表明本文提出的方法具有較小的輸出誤差和較強的抑制多址干擾的能力。
  5. Based on the criterion of maximizing the total average signal to interference plus noise ratio ( sinr ), the optimal subchannel allocation strategy is obtained in theory when random signature sequences are used. for its implementation, an iterative algorithm is proposed, which is similar to the water filling principle. by using the proposed algorithm, we obtain significant improvement on the performance of the system, and the transmission quality can be guaranteed

    根據最大信號干擾加噪聲比原理，分析得出了隨機特徵碼條件下最優的子通道分配策略，並提出了一種類似於灌水原理的子通道分配演算法，該演算法能在保證各個用戶傳輸質量的前提下，使系統的整體性能接近最優。
