您要查找的是不是：
- standard pilot tone system 标准导频系统
- Along with the estimation scheme, pilot tone placement is studied. 此外，还研究了所提算法中的导频分布问题。
- R. Negi, J. Cioffi; Pilot tone selection for channel estimation in a mobile OFDM system", IEEE Tran. On Consumer Electronics, Vol.44, No.3, August 1999. 李国松;周正欧;"固定波形时间保护间隔OFDM系统循环卷积特性研究";已被录用.
- pilot tone system 导频法
- There is great sexual differences of the tonetic register in the tone system. 双字调相对时长是前短后长模式。
- Since Tangxi dialect's original tone system did not have a high level tone, IVA syllables became their own tone type [55]. 由于汤溪方言的原声调系统中没有高平调，所以阴入字自成调类读[55]。
- As for IVB syllables' merger, the former tone system had two tones fairly close to [212], tone IB [313] and tone IIIB [14]. 至于阳入字的归向，原声调系统中跟[212]比较接近的有两个调，即阳平[313]调，阳去[14]调。
- It is better to group pilot tones together into clumps that are equispaced in the frequency domain. 可以证明，在快时变环境下，分组且每组等间隔分布于频域上的导频序列有着更好的系统性能。
- Swimming is the best way to tone up your body. 游泳是健体强身的最好方法。
- For Multi-Input Multi-Output (MIMO) Orthogonal Frequency Division Multiplexing (OFDM) systems with virtual subcarriers, conventional equispaced pilot tones are no longer applicable in some situations. 对于采用虚拟子载波的多输入多输出(MIMO)正交频分复用(OFDM)系统，传统最优的均匀分布导频序列在某些情况下是不可用的。
