常見例句雙語例句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)值得探討的問題。Various existing synchronization algorithm to estimate symbol timing offset and carrier frequency offset can be classified into blind and pilot-aided methods and algorithm based on cyclic prefix.目前，估計(jì)載波頻率偏差和符號(hào)定時(shí)偏差的算法主要有數(shù)據(jù)輔助的方法和非數(shù)據(jù)輔助的方法以及基於循環(huán)前綴的算法。 返回 frequency-offset estimate
