任意阶 LMSTDE 算法的 FPGA结构化设计
Structural design of arbitrary order LMSTDE algorithm in FPGA
摘要
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 addi- tive 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 method, which existed in software design, into FPGA, the arbitrary order LMSTDE algorithm was realized within the scope of FPGA recourses. Simulation and perform- ance experiment indicate that the parallel LMSTDE algorithm realized by structural design in FPGA increases operation speed and has flexible orders, and the definite anti-noise jamming performance is get without changing original algorithmrs convergence errors.关键词
