噪

Except for the great success of the conventional stochastic signal processing technology, there are some obvious deficiencies, especially when it's used in the complex nonlinear systems with addictive colored noise, or the parasitical noise, whose characteristics or parameters cannot be measured.

统计信号处理技术取得了很大的成功的后面，但是它本身又存在着明显的不足，尤其是处带有加性有色噪生的非线性系统、系统的寄生噪声的参数或者分布特征等无法取得的情况下，统计方法往往显得无能为力。

As for the rail, the peak value of rail rolling noise is chosen as objective function.

声屏障也是一种有效的降噪措施。

They ordered the pedlar to come up, but only to make fun of him.

但是从上房的酒席桌上，起来一阵喧噪和尖叫声——这就是他们所谓的唱歌；比这更好的东西他们就不会了。

It shows the phase image filtered by vector filtering method which can decrease noise is still clean, the distribution of power spectral density has no change, the spectral information loss after pretreatment though vector filtering was smaller than second mean filtering.

结果表明，相比二次均值滤波法，向量滤波法在降噪的同时，相位图依然清晰，它的功率谱密度分布没有明显变化，预处理后频谱信息的丢失远小于二次均值滤波。

For the problem that the suppression of co-channel interference and suppression of noise can't be balanced in signal-to-jamming and noise ratio maximization method for the linear precoding of multiuser multiple-input multiple-output downlink systems, an improved scheme that the term of noise variance is modified as a piecewise linear function is proposed, in which the balance between suppression of co-channel interference and suppression of noise can still be maintained even when the noise variance is a small value through piecewise modifying the term of noise variance, and thus the bit error rate and capacity of the systems are further improved.

针对多用户多输入多输出系统下行链路线性预编码的信干噪比最大化方法中，共信道干扰抑制和噪声抑制不能有效平衡的问题，提出将其中的噪声方差项修正为以噪声方差为变量的分段线性函数的改进方案。该方案通过对噪声方差项的分段修正，在噪声方差的值较小时依然能够保持共信道干扰抑制和噪声抑制间的平衡，从而使系统的误比特率性能和容量得到进一步提高。
