frequency offset

基本解释

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。

In this paper, the timing error is obtained by the autocorrelation characteristic of the pseudo noise sequence (PN-sequence) based on the special pilot symbols; then the frequency offset can be estimated grounded on the correlation of pilot symbols.
