  1. The wireless channel based on spread spectrum modulation can assure the digital video signal communication safe and withstanding the high noise disturbing condition

    而基於擴頻技術的無線通信通道,為視頻的傳輸提供了保密及抗干擾性能強等優點。
  2. 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。
  3. 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。
  4. Channel coding and modulation standard for digital video broadcasting - satellite

    衛星數字電視廣播通道編碼和調制標準
  5. Here we try out a hard way with video card to realize it. in the second place, we discuss some ways of digital modulation in transmission of image data, for example bpsk, qpsk, qam, and so on

    隨后,針對qpsk ,詳細討論了其基本原理和具體的實現演算法,並進行了模擬驗證,然後選用hsp50215數字上變頻晶元和hsp50214b數字下變頻晶元,設計了數字調制、解調器的實現方案。
