Abstract

The paper presents a design for open-loop carrier synchronization which is suitable for short burst communication at low SNR and it is easy to implement on FPGA platform. The proposed open-loop carrier synchronization is based on V&V and FFT algorithm which estimate both the frequency offset and the phase offset. We also implement a post-processing to solve the problem of phase ambiguity. The simulation results show that our proposed algorithm can work efficiently. Besides, the algorithm is implemented with a Xilinx XC7VX690T FPGA chip which achieves good performance under the condition of large frequency offset and low signal-to-noise ratio.
