peak to average power ratio meaning in Chinese

峰值对平均值功率比
峰值与平均功率比

Examples

  1. An optimal algorithm for reducing the peak to average power ratio of ofdm signal
    信号峰值平均功率比的优化算法
  2. Space - time block codes ( stbc ) based on orthogonal design has attracts enough attentions in its applications in mimo - ofdm systems for its full diversity exploiting and low coding / decoding complexity . these applications include not only system performance improvement , but also reduction of the peak to average power ratio in mimo - ofdm systems . under these backgrounds , this paper first studies space - time block codes under the single carrier , flat fading situation , discusses the encoding / decoding principle and its performance under different channels . then , the author focused on the performance of space - time codes under time selective and frequency selective channels , uncovered the fundamental cause of how maximum doppler shift and power delay profile influences the performance of space - time codes through deduction and simulation
    在上述背景下,本文以单载波,平坦衰落信道下的空时分组码为切入点,深入分析了其编译码原理和在不同信道情况下的性能;以此为基础,后文展开了对空时分组码在多载波,时间选择性和频率选择性衰落信道下的性能研究,通过理论推导和充分的仿真,揭示了空时/频分组码在时频选择性衰落信道中的性能变化的根本原因;在以上对多载波系统中空时分组码的研究的过程中,作者发现了空时分组码在降低系统峰平比方面应用的可行性,提出了一种降低峰平比的新方法。
