噪声分量 meaning in Chinese
noise components
Examples
- Frequency - domain equalization . at the same time discusses some key problems in ofdm : high ratio of peak - to - average power of output signals , problem of synchronization , channel estimation , adaptive bit , power and subcarrier allocation . emphasize on channel estimation , and present a new algorithm which can filtering more interpolation errors and noise . for the sake of improve the performance of resist narrowband noise and make efficient use of the spectrum apply malvar wavelet division
同时就ofdm系统中的一些关键问题如峰值平均功率比( papr )太高，同步问题，信道估计，信道、比特与功率必须动态分配进行了研究，着重研究了信道估计问题并提出一种改进的方法，能滤除更多的噪声分量和插值误差，提高系统的性能；为了提高抗窄带噪声的性能和提高信道利用率，用malvar小波变换实现了不等带宽分配。 - 4 ) a uniform crb expression of bearing estimation for spatially distributed sources in unknown noise environments is derived . more exactly , the crb performance of bearing estimation for spatially distributed sources in several typical spatially - correlated noises is evaluated theoretically and numerically , respectively . it is disclosed that the estimated errors mainly depend on space ambiguity between signal and noise components
4 )推导了未知噪声环境中空间分布源波达方向估计的统一的crb表达式，分析了几种典型的空间色噪声情况下分布源波达方向估计的极限性能，揭示了信号分量和噪声分量之间的空间混叠对分布源波达方向估计的决定性作用。
