频率分集 meaning in English
frequency diversity
Examples
- Two kinds of typical wideband signal , frequency modulation ( fm ) signal and frequency spread signal , is analyzed qualitatively with wideband ambiguity function
以宽带模糊度函数为工具定性地分析了两类典型宽带信号，即调频信号和频率分集信号。 - Furthermore , because the average power of transmitting lfmcw signal is the minimum peak power and the frequency diversity is high , it could not be detected easily
其次,由于lfmcw雷达发射其所需的平均功率是最小的峰值功率,并具有很高的频率分集性,因此不易被侦察设备探测。 - Finally , this thesis put forward the application of frequency diversity reception to the counteraction against the frequency selectivity decline in the airborne oceanic submarine laser communication system , and whose capability graph is educed through the simulation on the computer
文中提出把频率分集接收技术应用于对潜通信中，以达到抗频率选择性衰落的目的，并通过计算机模拟得出了其性能曲线。 - Space or multi - anntenna , diversity techniques are particularly attractive as they can be readily combined with other forms of diversity , e . g . , time and frequency diversity , and still offer dramatic performance gains when other forms of diversity are unavailable
空间或多天线分集技术由于可以与其它如时间分集,频率分集技术相结合,并在其基础上提供很大的性能增益,而成为一种很有吸引力的分集技术。 - It is very difficult to design a high - quality underwater acoustic data transmission system . in our study , we use frequency diversity and frequency - hopped technology . this method is an effective solution for the isi and signal fading
该方法起到保证mfsk传输系统使用频率中文摘要统使雨频率分集技术能得以有效的实现；并可用于提高mfsk信号检测精度，因此在频率信号检测中它有广泛应用意义，它是本文重要创新之处。
