Abstract

Digital modulation technology is widely applied. The principle of Binary Frequency-Shift Keying (2FSK) modulation is introduced and it is extended to Multi-Frequency-Shift Keying (MFSK). In this paper, a simple and easy modulation and demodulation method is presented. Frequency modulation uses baseband digital signal to control the number of sinusoidal signal per cycle data. Frequency demodulation uses the peak value of each group of signals to determine the corresponding baseband signals. The effectiveness of the proposed method is verified by simulation experiments.
