消波失真 的英文怎麼說
中文拼音 [xiāobōshīzhēn]
消波失真
英文
clipping distortion-
Computer simulation results show that the proposed algorithm reduces the signal distortion and the reverberation which are caused by misadjustment errors in the adaptive filter and the correlated component of the speech in the reference signal compared with a conventional adaptive noise canceller ( anc )
模擬結果證明nanc演算法有效克服了影響傳統自適應噪聲抵消系統（ anc ）性能的一些瓶頸，如兩輸入中的非相關噪聲，參考輸入中的信號成分與自適應濾波器失調誤差而產生的信號失真、回響等情況。Investigation on rf power amplifier imd detection and carrier cancellation
射頻放大器互調失真檢測和載波抵消的研究Hands - free speech communication is indispensable in audio and video conference systems, hot - line telephones and videophones, mobile radio terminals, digital isdn network etc. however, the control ( cancellation ) of the acoustic echo has always had a strong impact on the transmission quality in hands - free telecommunication ~ [ 1 - 3 ] conventional methods of acoustic echo control ( cancellation ), such as echo suppression or gain control, may lead to the degradations in speech quality or make the speakers feel uncomfortable
免提式話音通信在移動電話、熱線電話、車載電話及isdn網的電視電話會議等多種領域正得到日益廣泛的應用。但至今的免提式話音通信中，仍免不了受回聲引起的話音失真、甚至嘯叫等干擾，大大降低了免提話音通信的質量。由於聲回波對消問題尚未得到圓滿解決，實現高質量的免提式話音通信仍是一個極賦挑戰性的課題。In image processing, the wavelet of l2 ( r ) will cause distortion on the boundary by truncation error. in order to exterminate this phenomenon, one must modify the wavelet on the boundary. this gives rise to the wavelet on the interval
在圖像處理中， l ~ 2 （ r ）上的小波基因截斷誤差會在邊界處產生失真，為了消除這種邊界效應人們需要對其進行改進，這就產生了區間小波的理論。It also studies the influencing factors including sampling frequency, pd waveform, decline time, time intervals between pd pulses, mother wavelet, center frequency of interference, entropy threshold value and snr. in addition, it applies wavelet packet method （ wpm ） for non - stationary signal de - noising in on - line pd monitoring and analyzes the processing results under different pd waveform, sampling frequency and noise level. firstly, the curve of pd
基於小波包變換的非平穩信號消噪演算法（ wpm ）已較為成熟，本文將其應用於局部放電在線監測，通過研究其對不同局放波形、采樣率、噪聲水平下的處理效果，首次提出了理想白噪聲條件下提取局部放電信號的曲線，分析了各種因素對該演算法下信號失真的影響。Wavelets are becoming a key technique in the ongoing source compression standard jpeg - 2000. the positive arguments for advocating dwt in image watermarking are : preventing watermark removal by jpeg - 2000 lossy compression, reusing previous studies on source coding regarding the visibility of image degradations, and offering the possibility of embedding in the compressed domain
在小波域嵌入水印的原因是：可以防止由於jpeg - 2000有損壓縮而造成的水印消除；可以利用信源編碼領域對圖像失真的可見性研究成果控制水印的嵌入位置和強度；可以實現在壓縮域直接嵌入水印。分享友人
