• 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
  传统的信道估计算法需要训练序列使接收端的参数调整到理想状态，而本文提出的基于ica的信道估计的多用户检测算法不需要训练序列，它是利用下行信道的固有特点，用ica的盲源分离法估计出多径信道的卷积矩阵，从而从中提取出信道的延迟信息，仿真实验结果证明这种方法在节省了频谱资源的同时取得较好的估计效果，使得传统的接收机的误码性能得到了很大的提高。
