1) joint time-frequency synchronization
联合时频同步
3) combined synchronization
联合同步
1.
According to the characteristics of Unmanned Aerial Vehicle(UAV) data link synchronization technique,the paper analyses how the different offsets affect the demodulation,realizes the combined synchronization of frequency domain and that of time domain separately by using pilot and cyclic prefix,and proposes the plan of time-frequency two-stage combined synchronization.
依据基于OFDM的无人机数据链路同步技术的特点,分析了不同偏差对链路解调的影响,利用导频和循环前缀分别实现了频域联合同步和时域联合同步,并提出了时频域2级联合同步方案,数据仿真表明,2级联合同步不仅可以提高系统的捕获性能,还可以提高系统的跟踪精度。
6) joint time-frequency domain
时频联合域
1.
The results demonstrated that the modulation characteristics of the rotary blades can be seen more clearly in the joint time-frequency domain.
结果表明,在时频联合域可以更清楚地揭示直升机旋翼的调制特性。
