Abstract :
Carrier synchronization is the core part of modulation and demodulation system, which ensure the system fast, flexible and accurate processing the signal. The paper proposes a practical algorithm, combing LMS algorithm and Costas loop, to solve the problem of carrier synchronization based on software radio. This algorithm has been simulated in MATLAB and the result of the simulation is very good. At present, the carrier recovery algorithm has been applied in the practical project.
