| 摘 要： | 无论是军用还是民用，单信道时频重叠的通信与雷达混合信号的盲分离都具有迫切的需要，丈中提出一种利用小波多分辨分析特性，对其进行归一化处理，精确计算并匹配信号个数、载频、码速率、幅度等参数，并进行调制识别，最终实现盲分离的方法。该方法计算简单，不需要任何先验信息，且对信号能量相对强弱和信噪比范围均有较强的适应性和稳健性。仿真结果证明了该算法的有效性和较强的工程应用前景。 |

| Abstract: | The blind separation of time-frequency overlapped multi-signals in single channel is essential for both military and commercial communication applications.A blind separation method based on multi-resolution analysis is proposed.The method could estimate the number of components,calculates the symbol rates and carrier frequencies,and also recognizes the modulation types.It requires no prior information,and has even more adaptability and robustness.Computer simulations have verified its validity and prospect ... |
| Keywords: | multi-resolution analysis single channel modulation recognition parameter estimation blind separation |
