摘要 提出一种低复杂度内插滤波器的设计方法。该方法基于Farrow结构,以内插滤波器输出信号的均方误差最小(MMSE)为设计准则,从而保证最优性能。同时令内插滤波器系数对称化,以降低实现复杂度。仿真结果表明,在同等性能的基础上,优化的二阶内插滤波器和传统内插滤波器相比,复杂度降低了25%;在同等复杂度的基础上,优化的二阶内插滤波器和传统滤波器相比,输出均方误差性能有明显提高。 A low complexity design scheme of interpolation filter was proposed. This algorithm is based on Farrow structure, with minimizing MSE (MMSE) of interpolator output signal as its design rule, to guarantee optimum performance. In the meantime, the coefficients of interpolator are symmetrized to reduce complexity. The simulation result shows that contrasting with the same performance interpolator, the complexity of optimal two order interpolator can be decrease 25%, and contrasting with the same complexity interpolator, the performance of optimal two order interpolator can be better.
