frequency offset
基本解釋
- 頻率偏移；[通信] 頻率偏置
英漢例句
- 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(duì)多路QPSK信號(hào)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(duì)載波頻偏非常敏感，很小的載波頻偏都會(huì)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(gè)固有缺點(diǎn)是其對(duì)頻率偏移非常敏感，因此如何對(duì)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(gè)值得探討的問(wèn)題。
