frequency offset
基本解释
- 頻率偏移；[通信] 頻率偏置
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.
主要是解決數字接收機中，對多路QPSK信號解調時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重影響OFDM系統性能。 - 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的傳輸分集系統進行有傚的頻偏估計和校正是一個值得探討的問題。
