| 摘 要： | 提出了一种任意阶基于最小均方误差（LMS）白适应时延估计（LMSTDE）算法的现场可编程逻辑门阵列（FPGA）结构化设计方法．将原有的低阶次LMSTDE算法中速度受限的顺序迭代运算优化为只包含误差更新和权系数更新操作的全并行乘／加运算，并进一步分离为不依赖于阶次变量的功能运算单元，最后将软件设计中的结构化方法运用到FP...

| Abstract: | Method for optimized design and structured implement of arbitrary order LMSTDE(least mean square adaptive time delay estimate) algorithm in field programmable gate array(FPGA) was proposed.Time limited sequential iterative operation was optimized as parallel multiplicative and additive operations,which realized updating error and updating coefficients.Then the existing LMSTDE algorithm was separated into operation units,which was independent of filter order variable.Lastly,by importing structural design met... |
