| 摘 要： | 该文研究了高阶统计量（主要是三阶累积量）在自适应信号处理中的应用。探讨了线性系统自适应辨识的高阶累积量算法及其改进算法，并以自适应时延估计为例，推广了新算法在自适应信号处理中的应用。通过计算机仿真，对改进前后算法性能作了比较，还比较了它们同基于相关算法的性能差异，给出了仿真结果。

| Abstract: | This paper studies the application of higher order statistics in adaptive signal processing field,and developes a higher order cumulants algorithm and its improvement for adaptive identification of linear system, and also studies the other applications in the field by the instance of adaptive time delay estimation. In simulation, the performances of the improved algorithm with the old one,together with the traditional correlation algorithm are compared, and the simulation results are also given. |
