In this thesis , for the merits of high frequency spectrum utility factor and high - speed data communication , the ofdm is introduced into the underwater acoustic communication . combined with fec to combat the frequency - selective fades and isi in the underwater acoustic channel , high speed data transmission is realized by employing ofdm technology 本研究嘗試將ofdm技術引入水聲通信領域,利用該技術頻譜利用率高,多載波并行傳送的特點,結合信道編碼,以克服水聲信道多徑干擾引起的頻率選擇性衰落和碼間干擾,獲得高速率數據傳輸。

However , aoto marketing also is an utility factor that not only stimulates consummation , drags interior demonds , but also drives the auto industry to develop persistently and healthily . it can reveal well the developing foreground of the country ' s auto indudtry , which comes through the developing stage and the problem encountering inevitably ( economy , environment , science and technology , manufactureing level etc . ) also can base it to find countermeasure which suits the condition of country 而汽車市場營銷又是刺激消費需求、拉動內需,從而帶動汽車產業持續健康發展的實用研究學科,它能很好的揭示一個國家汽車產業的發展前景,應經歷的發展階段和必然遇到的問題(經濟環境、科技、制造水平等)并能據此找出適合國情的發展對策等。

Through example analysis , the relation between optimizing utility factor of berth and berth number of the port is set up and the reasonable utility rate of anchorage area is suggested in the paper . the results can be used in the optimizing design of the multipurpose ports 結合實例分析,研究探討了港口泊位利用率和錨地保證率的合理取值,得到了最優泊位利用率與泊位數的關系和合適的錨地保證率,為綜合性港口的優化設計提供了參考數據。

By using ofdm technology , we can redu ce the baud rate with a high frequency spectrum utility factor . another advantage of this technology is that the transmission can combat the intersymbol interference ( isi ) at the receiver without complex adaptive equalizer Ofdm既有較高的頻譜利用率,也有效地降低了碼速率,在不使用復雜的信道均衡技術的條件下仍然可以較好地克服接收時由多徑效應帶來的碼間串擾( isi ) 。
