摘 要: | MSK是一种特殊的2FSK信号,更适合于在非线性信道中传输,将MSK与普通的2FSK区分开来是很有必要的。为此,运用一种基于相位信息的2FSK与MSK的调制识别方法,来实现MSK与普通的2FSK的识别。通过计算机仿真表明,在SNR≥10dB的条件下,该方法识别率达到了100%。

Abstract: | MSK is one peculiar kind of 2FSK signals, more suitable in nonlinearity route. Separating MSK and common 2FSK is necessary. Based on the different phase information of 2FSK and the MSK, it is realized that they could be identified. Computer simulation shows that the recognition rates have got to 100% at SNR≥10dB. |
