宽带调制 meaning in Chinese
broadband modulation
wideband modulation
Examples
- For implement of wide band modulation , multi - carries and elimination of adjacent channel interference to satisfy ber requirement in wcdma system , which is most popular in 3g technology , the linearity requirement of the base station power amplifier becomes tighter
以wcdma为代表的第三代移动通信技术,为实现宽带调制、多载波应用,同时减小邻信道干扰以满足通信系统的误码率要求,对基站发射机功放的线性指标要求苛刻。 - Great breakthrough has been achieved in critical technologies applied in electronic information protector , e . g . scrambling cryptographic algorithm , broadband modulation , broadband amplification , etc . . with strong acquisition resistance , the protector can effectively protect the electronic information from interception
电子信息保护器，在加扰密码算法、宽带调制、宽带放大等关键技术上取得了重大突破，具有极强的抗征收能力，能够有效地保护电子信息不被征收截取。 - This is by two reasons : the first , as the development of military communication technologies , it transit from digital to software implementation , intelligence , broad band implementation and network implementation . many new technologies such as adaptive frequency hopping , burst communication , broadband modulation and complex coding accelerate the research about pertinence algorithms of signal sense and signal processing . the second , three hotspots of modern signal processing - spectrum estimation , high - order statistics ( hos ) and time - frequency analysis theory become more and more consummately and being used in communication jamming and anti - jamming field
应用于军事通信对抗的信号处理理论发展非常迅速，这得益于两个方面的动力：其一，军事通信的技术和手段不断更新，在数字化的基础上逐步走向软件化、智能化、宽带化和网络化，出现了自适应跳频、突发通信、宽带调制和复杂编码等新的实用技术，推动了具有很强针对性的信号侦测和处理领域的算法研究；其二，现代信号处理的三大热点? ?谱估计、高阶统计量方法、时频分析的理论和技术日臻完善，并逐渐应用于通信对抗领域。
