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。According to the trend, this paper introduces the technology of database and pc ' s serial port communication, which is adopted as the technology premise of wireless surveillance control system. and it illustrates the key technologies of how to realize the wireless surveillance control system. by making full use of its possible expansibility, flexibility and pervasive applicability, as well as the serial port communication technology, scada could help to transmit batch of data effectively, extend the ascii code serial port communication processing in the mscomm components and transmit the large - scale data stream
針對這一趨勢，論文在介紹了作為無線監控軟體系統的技術前提的數據庫技術和微型計算機串列口通信技術的基礎上闡述了實現無線監控軟體系統的各項關鍵技術，對利用數據庫系統對數據結構間的關系的嚴格定義和約束實現系統的可擴展性、靈活性與普遍應用性、利用計算機串列口通信技術實現批量數據傳輸、實現了數據的有效傳遞、 mscomm控制項中擴展ascii碼的串口通信處理和大型數據流的傳輸等項技術作了詳盡地說明，並對已完成的系統作出了評價，提出可以進一步改進的意見。And it described the composition of its software and hardware, including the process of data capturing, date memorizing, serial and usb communication to pc, lcd display, key input parts, speech recognition and alarm system, vehicle traveling data recorder software, pc software and so on
