  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. Digital sound broadcasting is a general term covering a wide range of systems and technologies, including eureka 147 and isdb - t, which are designed to replace frequency modulation broadcasting, digital radio mondiale, a possible successor to amplitude modulation, as well as iboc, which is intended to complement the existing am and fm services

    數碼聲音廣播?是一個統稱，技術上是分為不同的系統和制式，有取代fm廣播的eureka 147和isdb - t ，也有針對am廣播的drm ，和可以與am fm並存的iboc等系統，它們都有一個共通點，是現時的收音機並不適用。
