Guo Li · Harbin Gongcheng Daxue Xuebao/Journal of Harbin Engineering University · 2000
We set forth the theory of digital BPSK modem and figured out the diversified problems of realizing digital phase locked loop(DPLL),for example, error signal distil,phase track and loop filter.We also introduced some concept of digital radio, including digital direction synthesizer (DDS) and digital down conversion (DDC) and digital filter.A method was desccribed, i.e. complex programmed logic device (CPLD) to realizes high speed,digital BPSK modem.
