与SNR相关的网络例句 [注：此内容来源于网络，仅供参考]

When the launched SNR is more than the threshold, the cognitive network is an inter-user interference limited system, the base station selects the stochastic wave forming mode of a single beam and selects the user which has the maximum received SNR from the sub-scribers as a current communication object; when the launched SNR is less than the threshold, the sub-scriber network is a noise interference limited system. The base station selects the opportunistic SDMA of multi-beams and then selects a plurality of scribers with the maximum received SNR from the sub-scribers as the communication objects, thus realizing the maximization of system capacity.

当发射信噪比大于门限值时，认知网络为用户间干扰受限系统，基站选择单波束的随机波束成型模式，在从用户中选择接收信噪比最大的用户作为本次的通信的对象；当发射信噪比小于门限时，从用户网络为噪声干扰受限系统，基站选择多波束的机会式空分多址模式，在从用户中选择信噪比最大的几个用户作为通信对象，从而实现了系统容量最大化。

The main contributions in this area are summarized as follows,? The closed-form formula and its asymptotic form of system outageprobability are derived, through which it is shown that the outage probability decreased by a factor ofγ~(hereγdenotes the average SNR);? The closed-form formula of outage capacity is derived, through which weshow that 1 outage capacity increases with the increases of mean value of sytem SNR, and decreases with the increase of the variance of system average SNR; 2 in order to obtain higher outage capacity, the number of transmit antenna should be no more than that of receive antennas.?

特别的，针对多用户发送天线选择／最大比合并系统，主要贡献总结如下：·理论推导出中断概率的闭式解及其近似解，通过该近似解，可以得到中断概率以γ~的形式减少(这里γ是平均信噪比SNR)·推导出平均中断容量的闭式表达式，研究表明：1中断容量随着有效平均SNR的均值的增加而增加，随着有效平均SNR的方差的增大而减小；2为了获得更高的中断容量，发送天线的数目应当不大于接收天线的数目。

The findings: with the apparent dominant frequency of the Ricker wavelet rising, the detection SNR will get worse gradually, it is obvious that the variety of the SNR is slower during the portion of high frequency than during the portion of low frequency; in the usual range of seismic prospecting frequency, the SNR of the chaotic oscillator detection system could partially make up the amplitude attenuation aroused by the transmit of the seismic wave; the results could provide help for detecting the event constituted by aberrant wavelets.

本文以Ricker子波模拟地震子波，研究Ricker子波视主频变化的相应检测效果。研究结果：随着Ricker子波视主频的升高，检测SNR逐渐变差，在高频部分SNR的变化明显比低频部分缓慢；在通常地震勘探频率范围内，混沌振子系统检测SNR有可能部分补偿由于地震波传播引起的幅度降低；为检测由畸变子波构成的同相轴提供一定的可能。

SNR：信噪比

[摘要]针对基于基因表达谱数据的多类肿瘤亚型的识别与特征基因选取问题进行了研究;采用Gini指数与"信噪比"(SNR)指标相结合的方法,构建GSNR综合指标,剔除无关基因;然后采用BP神经网络设计复合分类器;最后使用SM算法,

SNR：信噪比 信噪比

数字无线传输中,一般不谈信噪比.信噪比(SNR)用于模拟传输,相当于数字传输(如QAM)中的误码率(BER).载噪比(C/N)越差,一般BER越差,直到不能同步.但是载噪比分带外载噪比和带内载噪比.带内载噪比的影响更大些.

SNR：信号噪声比

如果你采用音量调整对整个音频范围应用一个恒定的增益,声道产生的声音以及变调的声音就会越大,用户收听到的声音就会越刺耳,信号-噪声比(SNR)就会越低.
