  1. According to the carrier wave leakage and mirror wave interference in the signal generation, this paper analyzes the source of waveform distortion and its influence to signal spectrum and pulse compression result

    針對生成信號中存在的載漏和鏡像等失真，本文對波形失真來源及其對信號頻譜及脈壓結果的影響進行了全面分析與模擬。
  2. System scheme of speech coding plus spread spectrum communication was presented based on a full analysis of noise characteristic, attenuation characteristic and impedance characteristic of low - voltage power line. spread spectrum carrier ( abbreviated as ssc ) technology is adopted to overcome problems existing in signal transmission over power line. high quality, low rate mbe compression algorithm was used to complete speech encoding and decoding

    在對低壓電力線路的噪聲特性、衰減特性和阻抗特性三個方面充分分析的基礎上，本文提出一種語音編碼+擴頻傳輸的系統總體方案，採用擴頻載波（ spreadspectrumcarrier ，縮寫為ssc ）技術克服電力線傳輸信號存在的問題，採用語音合成質量高並具有較低碼率的mbe壓縮演算法完成語音信號的編解碼。
  3. Except, the error model of orthogonal modulation and double frequency technology were studied. third, the design and implementation of ultra wide band lfm generator were studied. an ultra wide band lfm pulse compression signal generator with 400mhz carrier and 300mhz absolute bandwidth was developed successful

    ?第三部分在理論分析的基礎上對超寬帶lfm信號源系統的設計和實現技術進行研究，成功研製出了中心頻率為400mhz ，帶寬為300mhz ，重復頻率為1khz ，脈寬為20 s的線性調頻信號。
  4. This arithmetic can detect the digital watermark without the original carrier image and the original watermark. experimental results prove that this arithmetic can hide the meaningful watermark efficiently in the carrier image, and it is robust enough to resist some image degradation processing such as clipping, jpeg compression, adding noise, image enhancing, filtering and so on

    實驗浙江工業大學碩士學位論文結果表明，該演算法可有效的將有意義的二值水印圖像嵌入到彩色載體圖像中，在抽取水印圖像時不需要原始載體圖像和原始水印圖像，並對裁剪、 jpeg壓縮、加噪、圖像增強、濾波等處理都有很好的抵抗力，具有較好的魯棒性。
