Abstract
Considering both large cost and high complexity of current carrier synchronization systems at low signal-to-noise ratio( SNR) ,this paper presents an adaptive carrier synchronization system design method based on the concept of “green communication”. First,the control parameter method is adopted to make the optimal performance scheme translate into suboptimal ones. Then,under the premise of satisfying fewer SNR losses,the suboptimal schemes are compared and some schemes with both small cost and low complex-ity are given. Simulation results show that compared with the optimal performance scheme,normalized pilot cost and complexity of the suboptimal ones can be reduced by 16% and 38% respectively,thus being ac-cordable with the concept of “green communication”.关键词
