Moreover, serious ISI (Inter-Symbol Interference) and ICI (Inter-Carrier Interference) can be readily circumvented by introducing CP (Cyclic Prefix).
而且,循环前缀的引入消除了符号间干扰(ISI),避免了信道间干扰(ici)。
The performance of channel estimator determines the performance of the MIMO systems because of the interference between various antennas and the inter-symbol interference (ISI).
MIMO系统中,由于各天线间干扰以及码间干扰等问题的存在,信道估计性能成为影响系统性能的决定性因素。
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.
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。
