声表面波小波处理器的计算机模拟与仿真

Computer Modeling and Simulation of Wavelet Processor Using Surface Acoustic Wave Devices

由于缺乏基本的计算机模拟与仿真手段,我们无法在试制样品前预估所设计的声表面波小波处理器的性能参数。因而,一旦设计参数出现偏差,所试制的样品的性能指标也就不可能满足设计要求,这不但延长研发周期,而且浪费大量不必要的研发经费。为此,该文介绍了一种对声表面波小波处理器进行计算机模拟与仿真的模型,并将其用于声表面波小波处理器的设计研制中,以期在样品试制前对其进行计算机模拟与仿真,直至模拟与仿真结果满足设计要求后再进行样品试制与测试,以尽可能地缩短研究周期,节约研究经费。理论与研究结果表明,采用该文介绍的计算机模拟与仿真模型对声表面波小波处理器进行计算机模拟与仿真,其模拟仿真结果与实测结果相比,其误差小于1%,基本能满足设计研发工作的需要。
