frequency offset
基本解释
- 频率偏移；[通信] 频率偏置
英汉例句
- Digitized demodulation of multi-channel QPSK signals often can not proceed normally due to the occurrence of unacceptably large frequency-offset.
主要是解决数字接收机中，对多路QPSK信号解调时所存在的较大载波频差的难题。 - 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对载波频偏非常敏感，很小的载波频偏都会严重影响OFDM系统性能。 - 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的一个固有缺点是其对频率偏移非常敏感，因此如何对基于OFDM的传输分集系统进行有效的频偏估计和校正是一个值得探讨的问题。
