  1. By adopting qam ( quadrature amplitude modulation ) modulation, we have researched and implemented a high - speed data broadcasting system compatible with dvb ( digital video broadcasting ) standard in the past years, and integrated and applicated the system into sdh / hfc ( synchronous digital hierarchy / hybrid fiber coax ) network for the first time in china

    經過多年的研究，開發出了符合dvb標準、採用qam調制方式的陽光網高速數據廣播系統，同時在國內首次實現了基於sdh hfc網路的高速數據廣播系統集成應用。
  2. As a high band - efficiency digital modulation scheme, dvbc ( digital video broadcasting of cable ) qam ( quadrature amplitude modulation ) modulator is widely adopted in the wide - band communication area, such as hdtv broadcasting, cable modem, microwave communication, satellite communication and so on

    正交幅度調制器（ qammodulator ）作為一種高頻譜利用率的數字調制方式，在高清晰度電視（ hdtv ）廣播、 cablemodem 、固定寬帶無線接入、衛星通信、數字微波傳輸等寬帶通信領域得到了廣泛應用。
  3. According the standard of digital video broadcasting for cable channel, this paper analyze, design and simulate a all - digital demodulator that receive high rate quadrature amplitude modulate ( qam ) signal in order to making the demodulator chip for qam signal that transmitted through the channel of cable television. the paper includes some contents as follows

    本文依照dvb - c傳輸標準，為了製作數字有線電視接收機中的正交振幅調制（ qam ）信號的全數字解調晶元，對qam信號的全數字解調器進行了分析、設計和模擬，主要包括以下內容：對數字下變頻進行了分析、設計和模擬。
