channel state information estimation 信道状态信息估计
This will result in the Inter Carrier Interference (ICI), and the synchronization error of the OFDM symbols will bring the Inter Symbol Interference (ISI). The channel state estimation will also be affected seriously.
OFDM载波频率偏差会带来OFDM的子信道间干扰(ICI),而OFDM数据符号同步的误差将会引入数据符号间干扰(ISI),同时还会对信道估计带来严重的影响。
