摘要
多进制数字频率调制(MFSK)是通信调制的一种重要方式。MFSK信号可用同步解调和包络解调两种方式进行,采用不同解调方式的MFSK通信系统具有不同的性能特点,重点讨论采用同步解调的MFSK通信系统的抗噪声性能。
Multiple Frequency Shift Keying （MFSK） is important in communication system. MFSK signal can be demodulated by synchronous demodulation and envelope demodulation. MFSK communication system has several features if it adopts different demodulation means.This paper emphasizes on the analysis of anti-noise performance of MFSK communication system which adopts synchronous demodulation.
