Description: Phase noise resulting in Common Phase Error
(CPE) and Inter-Carrier Interference (ICI) is a critical challenge
to the implementation of OFDM systems. Modeling phase noise
as a stationary Gaussian random process with the specified
power spectrum density, different from conventional approaches
which mostly relay on pilots to provide CPE estimation, we
explore the statistical characteristics of the sufficient statistics
then propose a pilot-aided decision-directed approach according
to maximum-likelihood criterion. Numerical results demonstrate
that the proposed algorithm enjoys 2dB gain at moderate SNR
and is quite robust against possible model mismatch

Description: 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扁平化架构及动态带宽分配等实现网络变
革，达到以下所述的网络性能，为移动宽带多媒体业务持
续发展提供技术保障。-Abstract:To meet the needs of mobile broadband
services,LTE is being deployed and becoming ma－
tured,which includes key technologies such as
OFDM,high-order modulation,HARQ,enhanced
multi-antenna technologies,fast synchronization
technologies,scalable control channel design,adap－
tive resource allocation,interference suppression
technologies etc.Moreover,the discussion on LTE-
Advanced has started,where technologies being
considered includes aggregate multi-carrier,high－
er-order MIMO,smart relay,heterogeneous net－
work,multipoint collaboration as well as enhanced
interference management.

Description: water filling without relay.We use simulation results to show the performance of the water filling algorithm. Simplify this question into a OFDM based communication network with one transmitter and one receiver. It is assumed that the total power of Pmax = 1 w and the total bandwidth is B = 5 MHz, which is divided into N=64 subchannels.
