例句与用法

  • Modulates the arguments , then adds the alpha of the first argument
    调制参数,然后加上第一个参数的alpha 。
  • As any other adaptive system , the following three steps are essential to our aofdm : estimating channel , choosing the right modulation parameters and signaling the chosen parameters
    和任何自适应系统一样,此系统包括信道估计,调制参数选择,以及信令三个主要部分。
  • But the spectrum efficiency of the traditional ofdm system is limited due to variance of channel parameters such as channel response and rms delay spread
    但是,决定通信系统调制参数的信道响应和rms时延扩展由于物体的运动或者环境的变化而动态变化,传统的静态确定ofdm系统调制参数的方法的频谱效率不够高。
  • Modulation format is one of the most important characteristics used to distinguish communication signals . knowing the modulation format and modulation parameters of a communication signal is the first step of correct demodulation
    调制方式是区分不同性质通信信号的一个重要特征,而要截获通信信号的信息内容,必须知道信号的调制方式和调制参数
  • Given a received communication signal , the objective of modulation recognition is to decide the modulation format and estimate the modulation parameters of the communication signal without any priori knowledge about the signal information content

  • Some modulation parameters , such as the carrier frequency and the symbol rate , can be estimated prior to the recognition of modulation types . such other parameters as the modulation index , the modulation frequency deviation , and the signal broadband can be further estimated after recognition
    部分调制参数如载波频率、符号速率在识别之前获得,在识别完成之后可以进一步估计调制指数、调制频偏、信号带宽等其余参数。
  • Usually dual sources ( radar and decoy ) have the same or alike modulation and position . in this dissertation , method of doa identification is studied in order to tracking individual radiation source correctly . the main efforts and results of this dissertation can be summarized as follows : 1
    本文重点研究在两点源(雷达和诱饵)空间张角很小、时域重叠、信号调制参数相同或相近的情况下, prs有效分选辐射源到达方向( directionofarrivals ,即doa )的方法,以实现对待攻击辐射源的正确跟踪。
  • Secondly , the paper researches blind estimation of signals parameters , including the carrier frequency , signal to noise ratio and symbol rate of digital modulations . thirdly , with the combination of parameters from early studies on the decision theory , a set of robust feature parameters are extracted from signal power spectrum and the power spectrum of the second and fourth power of signal . based on these parameters , the proposed scheme is able to recognize 12 types of common used modulations , namely ask 、 2fsk 、 msk 、 4fsk 、 psk 、 qpsk 、 / 4qpsk 、 8psk 、 am 、 dsb 、 ssb 、 fm
    接着,对信号功率谱、平方谱及四次方谱进行研究,针对通信中常用的调制方式,结合前人提出的基于决策理论中的特征参数,设计了一组对信噪比和信号调制参数不敏感的分类特征参数,利用上述参数完成了一种基于信号频域的识别方法,可以对ask 、 2fsk 、 msk 、 4fsk 、 psk 、 qpsk 、 / 4qpsk 、 8psk 、 am 、 dsb 、 ssb和fm这12种常用调制方式进行识别。
