Filtering signal in the wavelet domain, by the frequency components acceptable for ear from the original speech, is a simple and effective speech denoising method.

利用此特性对信号进行小波域滤波，可从加噪的语音中提取人耳所能接受的频率成份，是一种简单有效的语音去噪算法。

Another applied in filtering signal containing Gaussian white noise is computed directly by utilizing time-frequency spectrum of GST, which can enhance non-stationary signal and suppress noise.

后者直接应用广义s变换的时频谱实现，用于含高斯白噪声信号的滤波，达到了突出有效信号和压制噪声的效果。

It adopts space filtering technique to achieve suppression of jamming signal by comparing the output amplitude from the receivers of the main and auxiliary antennas.

它采用空间滤波技术，通过比较主、辅天线接收机的输出信号幅度，实现对干扰信号的抑制。

The Adaptive Wireless Engine, as it is called, is a device whose logic cells have been specifically designed to handle signal filtering, speech encoding, wireless communications protocols, and so on in other words, the sorts of things that mobile phones have to do.

ECONOMIST: Hardware goes soft

Building on the strength of the ClearPad 3200, the ClearPad 3400 features a redesigned Analog Front End (AFE), an integrated charge pump, and advanced filtering algorithms for industry-leading Signal-to-Noise (SNR) and Signal-to-Interference performance.
