摘　　要：在现有的单模板去卷积算法和多模板去卷积算法思想的基础上,提出了一种新的去卷积算法——改进多模板去卷积算法.该算法通过从实验测量数据中提取并优化多个模板信号,改变了传统算法中模板信号脱离具体实验环境提取的情况,所提取的模板信号综合体现了室内无线信道中的影响因素,改善了去卷积运算的有效性.经仿真试验证实,该方法去卷积效果明显,适用于不同环境下的室内信道建模.On the basis of current single-template deconvolution and multiple-template deconvolution algorithms, an improved multiple-template deconvolution algorithm is introduced. This algorithm retrieves and optimizes multiple template signals from measured data in experiments, whereas in traditional algorithms the retrieval of template signals is independent of actual experimental conditions. Sufficient factors are considered in this algorithm to significantly improve the effectiveness of deconvolution operation. A simulation test show that the proposed algorithm is suitable for modeling indoor channels under various environments.
