摘要
针对传统软件无线电系统无法兼顾系统性能与设计复杂度的问题,采用级联滤波的方法建立了一种新的系统模型,并以该模型为平台,在Matlab环境下仿真分析系统传输的有效性和可靠性.仿真结果表明,该模型在保证系统性能的前提下能有效降低计算的复杂度.
Aiming at the problem between system performance and design complexity in the traditional soft- ware radio system, a new model was made by cascade filtering method. Based on this model,the validity of transmission and system reliability were analysed by computer simulation on Matlab. The simulation results showed that the model could reduce design complexity on the premise of specified performance.
