摘要： 提出了一种基于自适应滤波算法的解调频移键控(FSK)信号的方法——自适应解调方法队(ADEM).文中以常用的最小均方误差自适应算法(LMS)为例,讨论ADBM对低速数据FSK信号的解调过程及其性能.实验结果表明,ADEM具有抗干扰性强、输出响应快、便于用数字信号处理(DSP)技术实现等特点,并且易于推广应用.

Abstract: This paper presents a new method for demodulating the frequency shift Keying (FSK) signals, the adaptive demodulation (ADEM) method. The commonly used least mean square (LMS) error adaptive filtering algorithm is employed for studying the demodulating procedure and the performance of the ADEM scheme. It is indicated by simulation experiments that the ADEM has many advantages over conventional ones, such as the powerful anti-noise ability,the small transfer delay, and the convenient implementation with DSP technology. The idea and Principle of the ADEM can also be applied to other modulation modes.
