Abstract
In the Burst-mode DSSS receiver, we need to achieve carrier synchronization in short preambles after the DSSS signal is captured. , to achieve this objective which combines with our project; we use a fast carrier synchronization scheme of FFT+FLL+Digital Costas loop; and we simulate the scheme on the Matlab under the required SNR of our project indicators; the result of the simulation indicates the scheme can achieve carrier synchronization in required preambles, realize the correct demodulation of user's data; the scheme has the characteristics of a big rage of modify frequency, fast speed to achieve carrier synchronization, simple structure, and can operate steadily on the environment of low SNR.关键词
