This paper presents a noisy speech recognition system with added background noise so that the recognition system can work well both in quiet and noisy environments 然而，当实际环境中有噪声存在时，语音识别系统性能急剧下降。
Using kinds of typical background noise , it studied few of factors in the system which would affect the system ' s function 主要对fx - lms结构中可能影响系统噪声抵消性能的因素(辅助通道和误差通道) ，在典型的背景噪声下，进行了比较研究。
What is more , people with normal hearing can pick up relatively quiet sounds ? say , an interesting conversation ? amid loud background noise 不仅如此，拥有正常听力的人，还能从吵杂的背景噪音之中，听出相当细微的声响（比如一段有趣的对话） 。
The planet vibrates at a very low frequency ? too low for our ears to pick up , but enough that geologists get an annoying background noise on their sensitive instruments 行星振动的频率很低，我们耳朵很难分辨出，但在地理学家灵敏的仪器上却会收到一个非常令人讨厌的背景噪音。
Including the identification of noise sources , the effort of the background noise , and the properties of environment , the procedure for noise control is developed 并且就上述之各个要素设计出进行噪音污染防治与改善案之可能流程，以描绘出钢铁厂整厂噪音污染防治与改善之模式。
The result of his labours might be mere background noise , but he liked even that , especially if it could be run through big loudspeakers to a baffled audience 他无休止的劳作也许最终只是得到了一些背景噪音，但他却恰好喜欢这样，特别是喜欢这种噪音能用大扩音器播放给听众并引起人们烦躁。
Strong background noises are eliminated effectively by multi - level amplifier and filter , and un - anamorphic eeg can be acquired and be displayed synchronously in computer 该方案通过多级放大和滤波，有效地消除了脑电信号强大背景噪声的干扰，从而实现微弱脑电信号的放大，采集到准确清晰的脑电波形。
As the intensity of radio - frequency interference in our environment grows , we have to raise the volume of radio signals so that they can be heard over the electromagnetic background noise 由于环境中的无线电波干扰日渐增强，因此我们必须提高无线电讯号的强度，才能从背景的电磁杂讯中分辨出讯息。
This paper also studies the statistics characteristic of signal , clutter and noise after the system disposal , and generates target data and detecting background noise using the simulated system 研究了信号及杂波、噪声在信号处理之后的统计特性,并通过仿真系统产生了目标回波数据及检测背景噪声。
In the paper , diffuse channel characteristics is studied , multiple dispersion and background noise is detailedly analyzed , based on which the network buildup and protocol structure are analyzed 在信道研究的基础上,分析了无线光局域网的组网原理和协议结构。为实现无线光室内组网提供了解决方案。
