Abstract:

In this paper,a method for generating the BPSK signal by using AD9854 controlled by FPGA is proposed,including the construct of the periphery,the configuration of each register,the calculation of the amplitude,the phase,and the frequency tuning word.Finally,an example of BPSK signal generation is given,and the correctness of the design in this paper is also verified.
