backward interpolation

基本解釋

Backward interpolation has advantages of easier calculation and fewer errors.
二次插值的外插法具有計算簡單、誤差較小的優(yōu)點。
Then, the data parallel implementation scheme of zero-order interpolation and first-order interpolation of backward mapping are discussed.
幾何操作反向映射的零階內插與一階內插的數(shù)據(jù)并行實現(xiàn)方法；
It can improve the real-time of APF effectively by using backward interpolation to predict harmonic. The simulation results show the effectiveness of this algorithm.
提出用改進后的二次插值的外插值法對諧波進行預測，可以有效地提高APF的實時性，仿真結果表明了這種算法的有效性。
