近年来随着移动互联网业务和物联网业务的兴起与
发展,用户对移动宽带业务需求越来越旺盛,对移动通信
网络的接入速率和质量要求也越来越高,原有基于码分多
址(CDMA)的3G及其增强技术未来将无法满足业务发展
需要,因此3GPP及3GPP2组织自2004年开始启动长期
演进(LTE)/空口演进(AIE,后改名为超移动宽带UMB)项
目,旨在通过引入一些关键技术,如正交频分复用(OFDM)
调制技术、多入多出(MIMO)技术、混合自动重传请求
(HARQ)、全IP扁平化

When a UE moves away the serving eNodeB
(eNB) and becomes closer to the neighbouring eNB (see
fig.1), the strength of desired received signal decreases and
the ICI increases.The impact of ICI in LTE downlink can be
analysed according to the r

The reference turbo decoder supports the Successive Interference Cancellation (SIC)
technique, which may be employed by the basestation eNB receiver as the channel
coding equalisation technique to improve the throughput performance in the LTE-A
