Description: 数，都需要通过导频序列来获取同步信息，而且为了达到更好的均衡效果，OFDM 系统也要进行简单的频域均衡。此外，OFDM与SC．FDE的帧格式也十分相似，都 需要添加CP(SC．FDE采用UW)来吸收前面帧的干扰并满足循环卷积特性。 由于OFDM在结构和原理上都与SC．FDE十分相近，可以设计一种双模式系统。 双模式系统仅仅改变IFFT模块在发送端和接收端的位置就可以同时支持两种系统传 输。两种系统都可以通过编码、自适应调制和空间分集提高性能。而且，

Compared to OFDMA (mainly used for the downlink), the biggest advantage lies in its low peak-average power ratio (ie, PAPR). This procedure, including OFDMA, SC-FDE (single carrier frequency domain equalization), as well as SC-FDMA procedure, the receiving end the use of classical ZF and MMSE detection algorithm, procedures dapper, very classic, convenient in the field to learn and research.

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: INTER-CARRIER INTERFERENCE CANCELLATION FOR OFDM SYSTEMS:
Orthogonal Frequency Division Multiplexing (OFDM) is an emerging multi-carrier modulation scheme, which has been adopted for several wireless standards such as IEEE 802.11a and HiperLAN2. A well-known problem of OFDM is its sensitivity to frequency offset between the transmitted and received carrier frequencies. This frequency offset introduces inter-carrier interference (ICI) in the OFDM symbol. This project investigates three methods for combating the effects of ICI: ICI self-cancellation (SC), maximum likelihood (ML) estimation, and extended Kalman filter (EKF) method. These three methods are compared in terms of bit error rate performance, bandwidth efficiency, and computational complexity. Through simulations, it is shown that the three techniques are effective in mitigating the effects of ICI. For high values of the frequency offset and for higher order modulation schemes, the ML and EKF methods perform better than the SC method.
