    該系統將成組技術的分類編碼原理和計算機輔助設計技術應用於擠壓鋁型材的產品開發設計和產品圖紙的管理中，不僅可以極大地提高產品設計質量、縮短產品開發周期，還可以減少重復繪圖工作及規范制圖方法；同時，利用計算機存儲空間大、運行速度快的優點，可實現對已有產品圖紙的集中管理和快速檢索。利用計算機輔助產品開發，不僅能以高質量、低成本的產品迅速滿足市場需求，還可為工廠進一步實施計算機應用工程（如后續生產管理等）奠定良好的基礎。
  2. This thesis analyzed the error performance of mfsk and mpsk modulator in hf with optimal receiver, studied the shortcoming and strongpoint of several typical short - wave data transmission systems and their performance over fading and intersymbol interference channels. the theory and key technical of adaptive modem is discussed. in the last, an efficient modulation scheme - block coded modulation is introduced into hf radio systems to improve the efficiency of hf data transmission, this paper also proposes a hf data transmission system scheme composed of a block coded modulator and a decision feedback type adaptive equalizer

    本文在對短波數傳兩種常見調制方式fsk及psk最佳解調性能分析的基礎上，討論了幾種採用典型調制技術的短波數傳系統（如時頻調制、多進制頻移鍵控慢跳頻、 chess系統）原理、優缺點以及抗衰落和抗符號間干擾的性能；分析了自適應串列數傳系統抗短波通道衰落和多徑干擾的原理、關鍵技術；在本文的最後引入一種有望解決短波數傳系統低效率狀況的調制方式bcm -分組編碼調制，給出了一個採用bcm技術與自適應均衡技術相結合的短波數傳系統方案，並通過計算機模擬進行了初部驗證。
  3. The proposed md mesh - based motion coding methodis then combined with the pairwise correlating transform, and acomplete md video coding scheme is proposed. further measures are takento reduce the mismatch between the encoder and decoder that occurs whenonly one description is received and the decoder reconstruction isdifferent from the encoder. the performance of the proposed scheme isevaluated using computer simulations, and the results show, compared toreibman s md transform coding mdtc method, the proposed schemeachieves better redundancy rate distortion performance

    數據重傳必然會引起延遲，因而在需要很短延遲的應用中是行不通的，如雙向無線通信同時在以廣播方式進行數據傳輸時也是行不通的當有大量突發錯誤時，糾錯碼如分組糾錯碼block code及卷積碼convolutional code無法在不產生額外延遲及需要額外運算的前提下對數據提供足夠的保護而錯誤掩蔽的性能則受接收到數據與丟失數據之間的殘留相關性大小的影響。
  4. The combination of advantage in the two technology can solve the problem of transmission qos and bandwidth limitaion of wireless relay network. wu wei ( computer application technology ) directed by prof

    這種低比特率語音編碼和aal2在支持實時、可變速率、短分組業務應用中的優勢相結合的方案，可解決通信網中無線中繼存在的傳輸質量和帶寬受限的問題。
