基于FPGA的高速自适应格型滤波器的实现

摘要

Considering numerical characteristics and real-time performance requirements of adaptive filters for the high sensitivity and high speed digital signal processing, a pipeline optimization approach based on the technology of delay leading transfer and retiming is proposed to improve GALJP algorithm. The new algorithm implemented in the FPGA can achieve high operating frequencies with small loss of the filtering performance.%针对高速高灵敏度数字信号处理时对于自适应滤波器的数值特性和实时性的要求,在一种自适应格型联合滤波器的基础上提出算法改进,采用驰豫超前流水线技术和时序重构技术,在损失较小滤波性能的情况下,在FPGA中实现算法并可以达到较高的工作频率.
