大的峰值会使功率放大器饱和,在子载波间产生交调干扰和导致能量的带外弥散。
These large peaks cause saturation in power amplifiers, leading to intermodulation products among the subcarriers and disturbing out of band energy.
对于多载波系统,载波频率的偏移会导致子信道之间产生干扰。
The offset of carrier frequency can cause interference between subchannels in a multicarrier system.
当存在同步错误时,子载波之间的正交性遭到破坏,从而引起严重的载波间干扰,使解调性能大大下降。
When a synchronization error exists, the orthogonality between sub-carriers can't be maintained, serious inter-carrier interference is introduced and demodulation performance will be degraded greatly.
定时偏差会导致码间干扰,频率偏差会破坏子载波间的正交性,引起子载波间干扰,从而使系统整体性能急剧下降。
Timing offset causes inter-symbol interference, and frequency offset would destroy the orthogonality between subcarriers, causing ICI, which lead to a sharp decline in overall system performance.
在上行链路中每个用户由于载波频率偏差而存在潜在的不同步,这样使子载波之间失去正交性,从而在基站接收端产生多用户间干扰。
However in uplink channel, each user has its own frequency offset which leads to a loss of orthogonality among the sub-carriers and multiuser interference at the base station receiver.
