Based on the introduction of the space-time time-frequency-shift keying (ST-TFSK) systems, the paper deduces the noncoherent ML decision metric at the receiver with the knowledge of relative delay.
在介绍空时/时频调制(ST-TFSK)系统原理的基础上,该文推导了在接收端已知相对时延条件下的非相干ML判决度量,讨论了在接收端未知相对时延条件下信噪比与系统误码率性能的关系,并将其结果与空时/频移键控(ST-FSK)系统的情形相比较。
3) Relative time delay
相对时延
1.
In the multi path communication scenario,it is needed to estimate the two dimensional angles and relative time delays of each multi path ray.
在多径传输的情况下 ,经常需要估计各路径的二维波达方向角度及相对时延 。
4) absolute group delay

5) trace-to-trace time delay
道间相对时延
6) group delay ripple
群时延
1.
It is demonstrated that the apodization sharpness parameter plays a more important role in the behavior of the mean dispersion,group delay ripple and some other spectral responses even than the type of apodization profile itself.
75时,色散均值与理想色散之间的偏离量最小,群时延影响较小,反射带宽较大,且光栅长度较短。
2.
The positive hyperbolic-tangent profile is taken for example and it will demonstrate that a proper selection of the apodization strength factor can effectively improve the results obtaining minimum deviation of the dispersion from the required value,maximum reflection bandwidth and minimum group delay ripple impact.
以双曲正切函数为例,证明适当选择切趾强度参数,可以获得最小色散背离、最大的反射带宽和最小的群时延影响。
