三角函数内插法分析及其FPGA实现

Analysis and FPGA Implementation for Trigonometric Polynomial Interpolation

文章介绍了一种用于符号同步的三角函数内插法,给出了该算法的仿真结果,同Far-row结构的内插滤波器相比较,该算法有着简单的实现结构和高的内插精度。文章最后给出了三角函数内插法的一种FPGA实现方法及其综合结果。

This paper addresses a novel Trigonometric Polynomial Interpolation for Timing Recovery and its simulation result with maflab. Compared with Farrow structure filter, this approach produces a particularly simple implementation and high interpolation performance. At last, this paper describes a FPGA implementation approach and results for trigonometric polynomial interpolation.
