  1. 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。
  2. Because of radio wave propagating along the ducts with enhanced fields on the order of the free - space field, the problems of the co - channel interference are more complicate for communication systems with the results of intersystem interference and the formation of other system, and therefore affecting the determination of the coordination distances or the optimization of the distribution and separation of delay, and for surveillance system such as radar system the problems can be radar holes or the extensions of detect range

    對于通信電路,它使系統間的相互干擾問題變得復雜,既可能幹擾其他系統又可能形成另外的系統,從而影響系統的有關參數如中繼電路的最佳組合(分佈、間隔)和協調距離,對于探測系統產生的則是雷達空洞、超視距探測等問題。這些問題對相關無線電系統特別是軍事應用系統可能是致命的,因而以波導傳播為代表的反常傳播特性研究受到極大重視。
