Open publisher page 0 citations

Abstract

We introduce a kind of new QAM modulation which makes phase switch into phase continuous change.The computer simulations demonstrate phase continuous QAM can successfully raise frequency using ratio.The majority of function in modulator are realized by FPGA resource,which can enhance the system's reliability,and reduce its size.Because of the particular phase transformation in phase-continuous QAM,double-channel design is successfully applied to coming into being transition-phase and main-phase alternately.
