delay spread

基本解释

• 延迟扩展

英汉例句

双语例句

• When the data rate is high, there is ISI because the signal duration is shorter than the channel delay spread.
  在较高的信号传输速率下，传输符号的符号周期小于信道的时延扩展，从而产生ISI。
• If the length of its cyclic prefix is larger than the delay spread of transmission channel, we can get a simple frequency equalizer to demodulate OFDM signal.
  对于传统的OFDM系统来说，如果循环前缀的长度大于信道的时延扩散值，则可以通过简单的频域均衡来解调OFDM信号。
• This paper studies the application of minimum description length (MDL) criterion for estimating root-mean-squared (RMS) delay spread (RDS) for MIMO OFDM systems.
  研究了MIMO OFDM系统中最小描述长度（MDL）准则在均方根时延扩展估计中的应用。
