Description: Abstract—In this paper we present an initial performance
evaluation of the 3GPP UTRA Long Term Evolution (UTRA
LTE) uplink with baseline settings. The performance results
are obtained from a detailed UTRA LTE uplink link level
simulator supporting OFDMA and SC-FDMA schemes. The basic
transmission scheme for uplink direction is based on singlecarrier
transmission in the form of DFT Spread OFDM with
an MMSE receiver. Two antenna configurations, SISO and 1x2
SIMO are considered in the analysis of spectral efficiency in
addition to Adaptive Modulation and Coding (AMC) and L1-
HARQ. For assessment purposes, the performance results of
SC-FDMA are compared with OFDMA. It is shown that 1x2
SIMO greatly increases the spectral efficiency of SC-FDMA
making it comparable to OFDMA, especially for high coding
rate. Furthermore, SC-FDMA has a flexibility to increase BLER
performance by exploiting frequency diversity.

Description: 本文介绍了基于交织分集多址的层调制（LM），并对比了该调制方法和MPSK，QAM等的性能。-Applying LM to 3GPP LTE downlink, we compare LM to M-PSK QAM modulation. Numerical results show that the LM can achieve superior performance over M-PSK/QAM. The performance gain over QPSK, 8PSK and 16QAM is 1.1dB, 2.2dB and O.6dB,
respectively.

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－
