A VHDL Design and Realization of 2FSK Modulator Based on DDS
Yanh Yan · Journal of Zhongyuan University of Technology · 2009
Aim that traditional 2FSK modulation way is easy to have phase hits and don't have higher bandwitdth efficiency,a 2FSK modulation way based on the technology of direct digital frequency synthesizer is presented in this paper,overall design and various functions module design methods are given,and is realized in the Altera Cylone experiment board.The experiment result indicated that this modulation have the continuous output phase and strong anti-interference ability.
