一种新的MPSK信号识别算法
A New Algorithm for Classification of MPSK Signals
摘要:
针对多径信道中的MPSK信号的分类识别,提出一种新的识别算法。该算法在高阶累积量方法的基础上引入小波变换,利用小波去噪的相关结果有效地抑制了加性和乘性噪声的影响,与现有的其他方法相比,本文所针对的信号模型更普遍,有更广泛的适用范围。后面的试验证明方法的有效性和实用性。
Abstract:
A new algorithm is proposed for classification of MPSK signals. The algorithm is based on wavelet transform and high order cumulants. Compared with other existing algorithms, the proposed al-gorithm reduces the effect of additive Gauass noise and multiplicative noise, therefore, be of more generality. Theoretical analysis and computer simulation justify the robusticity and the efficiency of the new classification algorithm.
