  1. Our object is an intermediate frequency modem of a software defined radio transmitter - receiver of multi - service, multi - modulationmode and multi - processdatarate. first, related software defined radio theory is introduced ; later, channels of transmitter - receiver are designed with consideration of data format, modulation, fec, interwaving. and scrambling ; emphasis is placed on theory and implementation of an audio compression algorithm cvsd ( continuous variable slope delta modulation ) and a fec technique convolutional coding - decoding

    本文首先介紹了相關的軟體無線電理論；然後完成了包括數據格式，調制方式，糾錯碼方式，交織器和擾碼器等部分的中頻數據機通道設計；接著著重介紹了系統中使用的音頻壓縮演算法cvsd （連續可變斜率增量調制）的原理和實現，以及作為前向糾錯碼的卷積碼編碼理論和編解碼的高效實現。
  2. Based on comparison between the parallel - parallel and parallel - serial combination ttfc, a novel two - transistor forward converter with parallel - serial / serial combination is proposed. this converter reduces greatly the current overshoot of the primary side switches and the voltage overshoot of the rectifying diodes. moreover, the size and weight of the converter can also be reduced by interleaving technique and increasing frequency

    本文在對並-串型和並-並型雙管正激組合變換器進行了詳細比較研究的基礎上，提出了一種新型並-串串型雙管正激組合變換器，該組合變換器可以大大減小原邊開關管的電流應力和副邊整流電路中二極體的電壓應力；通過交錯控制及提高開關頻率，大大提高了變換器的功率密度。
  3. A cross - verification mechanism is worked out for detecting facial features on moving pictures by merging the technologies of both image analysis and motion analysis. it provides a solution to the problem of error - correction and feature estimation and makes it possible to detect facial features on video segment at a correction ration of 98 %, thus paves the way for the application of content - based retrieval and video encoding

    2 、提出圖像分析和運動分析相結合的交叉驗證方法，實現了活動圖像人臉特徵檢測中的自動糾錯和特徵估計機制，從而使視頻中人臉特徵自動檢測的正確率達到98 %以上，為基於內容檢索和視頻編碼的應用開辟了道路。
