摘要
研究了MSK信号的循环平稳特性及其循环谱密度函数,从循环谱的角度分析了MSK信号的的循环谱噪声抑制特性,仿真结果表明,利用MSK信号的循环平稳特性,可以用来在低噪声环境下检测信号。
The paper studies the cyclostationary characteristics and spectral correlation density function of the MSK signal,then analysis the characteristics of the noise suppressing.simulations show that the cyclostationary characteristics of MSK can be used in detecting signal in low noise environment.
