基本解釋

• 頻率偏移；[通信] 頻率偏置

英漢例句

雙語例句

• Digitized demodulation of multi-channel QPSK signals often can not proceed normally due to the occurrence of unacceptably large frequency-offset.
  主要是解決數(shù)字接收機(jī)中，對多路QPSK信號解調(diào)時(shí)所存在的較大載波頻差的難題。
• But because of the sensitivity to the carrier frequency-offset, very small frequency offset will destroy the performance of the OFDM system, badly.
  但是，OFDM對載波頻偏非常敏感，很小的載波頻偏都會嚴(yán)重影響OFDM系統(tǒng)性能。
• However, OFDM systems are very sensitive to frequency-offset. Therefore, it is necessary to estimate effectively and to compensate frequency-offset in the systems.
  可是OFDM的一個固有缺點(diǎn)是其對頻率偏移非常敏感，因此如何對基於OFDM的傳輸分集系統(tǒng)進(jìn)行有傚的頻偏估計(jì)和校正是一個值得探討的問題。
