软件无线电中信号调制方式识别的研究与应用

Study and Application of the Identifcation of Digital Modulation in the Software Radio

基于软件无线电数字信号通用解调模型原理,分析了软件无线电系统中的数字信号调制方式的自动识别算法,特别是对正交调制的调制方式的识别,在解调同时自动识别调制方式。最后研究和分析识别方式的最佳判决门限,以及识别出错率与信噪比的关系。

A steady state model of the auto-identification of digital modulation in the software radio and the algorithm is especially used in the identification of digital modulation in the quadrature demodulation ?It gives the identification in modulation and gives the limits of optimal judge door and the relation between the identification error probability and the Signal-to-Noise.
