| 摘 要： | 为了提高线性定常系统的仿真精度和速度，提出了基于快速DCT的线性定常系统高精度仿真算法。该算法与传统的仿真算法原理不同，它以数字信号处理方法和多项式多点快速求值算法为基础，采用了特殊的误差补偿算法。理论分析和上机仿真实践表明，该算法精度高，对于阶次高的系统计算量很小，尤其适于大规族并行计算。

| Abstract: | To improve the simulation precision and speed of LTI system, the highly precise simulation algorithm of LTI system based on Discrete Cosine Transform(DCT) is proposed. This algorithm is founded on the digital signal processing methods and the polynomial multi-point fast evaluation algorithm, applies the special error compensation and is different with the conventional in principle. It shows by the theoretical analysis and practical simulation on computer that this algorithm is characteristic of high precision, very small quantity of calculation to high exponent system and especially suitable for massive parallel computation. |
