  • 摘要: 多進(jìn)制頻移鍵控(MFSK)信號(hào)被廣泛應(yīng)用于各種軍用、民用通信系統(tǒng)中。針對(duì)其調(diào)制參數(shù)估計(jì)，現(xiàn)有的方法大多基于小波變換，但其存在抗噪性能差，參數(shù)不易選取等問題。通過對(duì)語圖不確定原理的研究，該文提出一種語圖邏輯與運(yùn)算方法，并引入波形變換理論改善時(shí)頻變換波形占空比，提高了估計(jì)算法的信噪比門限，完成低信噪比下MFSK信號(hào)調(diào)制參數(shù)的自適應(yīng)盲估計(jì)。仿真表明，所提算法在抗噪聲、頻偏性能及參數(shù)選取魯棒性上均優(yōu)于現(xiàn)有常用算法，適合工程實(shí)踐。
    Abstract: MFSK signal is widely used in military and civil communication systems. For the issues of its modulation parameters estimation, wavelet transform theory is mostly adopted in current algorithms. However, the anti-noise performance is poor and parameters are difficult to choose. On the research of indeterminacy theory of spectrogram, a strategy for spectrograms modifying is proposed and the waveform transforming theory is drawn into to upgrade the duty cycle. As the result, the anti-noise performance is improved and the self adaption blind parameter estimation is achieved. The simulation results indicate a better performance of proposed algorithm than current algorithms in anti-noise and frequency offset performance and robustness of parameters which makes it a better choice for engineering practice.
