现代社会发展要求通信系统功能越来越强，性能越来越高，构成越来越复杂；另一方面，要求通信系统技术研究和产品开发缩短周期，降低成本，提高水平。这样尖锐对立的两个方面的要求，只有通过使用强大的计算机辅助分析设计技术和工具才能实现(Social development of modern communication systems require increasingly strong, the performance is getting higher and higher, which constitute more and more complex On the other hand, communications systems technology research and product development to shorten the cycle, reduce costs, improve the level. This in sharp opposition to the two requirements, only through the use of powerful computer-aided analysis and design techniques and tools can be achieved)

Frequency-dependent-noise-attenuatio
地震资料 数据处理 分频去噪 模块 主要压制随机噪音 异常振幅 野值 大值
方法特点：1 针对性强，主要去除随机噪音；2 随机噪音识别能力强，达到了较高的去噪水平；3 具有自适应性，能根据不同位置的不同特点统计识别噪音；4 振幅保真，对有效信号的保护性好；5 操作者可根据经验选择参数组合灵活去噪，达到较好的结果。
应用对比：为了展示本模块的去噪效果，所选取的对比对象是某知名成熟商业软件的分频去噪模块，其去噪效果在当前诸多成熟软件模块中是佼佼者，在地震资料处理界具有很好的口碑。
通过对比，说明本模块：1 针对性强，主要去除随机噪音和异常振幅等。2 随机噪音识别能力强，达到了较高的去噪水平。3 具有自适应性，能根据不同位置的不同特点统计识别噪音。4 振幅保真，对有效信号的保护性好。5 操作者可根据经验选择参数组合灵活去噪，达到较好的结果。(Frequency-dependent noise attenuation
seismic data, processing module, is mainly to suppress random noise, denoising abnormal/large amplitude values
Method of characteristics: 1 targeted, mainly to remove random noise 2 random noise and strong ability to identify , reach a higher level of de-noising 3 is adaptive , able to identify the noise statistics according to the different characteristics of different positions 4 amplitude fidelity , the effective protection of the signal is good 5 denoising operator flexibility to select the combination of parameters according to the experience , to achieve better results .
Application contrast: To demonstrate the effect of the de-noising module , the selected object is a well-known comparative commercial software divide mature noising module de-noising effect is the current leader in many mature software module in seismic data processing industry has a good reputation.
By contrast, the description of the module : a targeted, mai)
