| Abstract: |
| The principle of early-late gate synchronization technique is analyzed. Synchro
nization for external symbols is achieved in a single chip of FPGA, and the local coherent ca
rrier is generated. On this base,coherent BPSK modulation of external symb
ols is realized.Simulation result shows that the designed module can output BPSK
signal and meets the requirement of engineering application. |
