Description: Single Carrier FDMA又称SC-FDMA或者DFT-Spread-OFDM是3GPP LTE最新提出的适用于上行传输的一种新方案。相对于OFDMA（主要用于下行），其最大的优势在于低峰值平均功率比（即PAPR）。本程序包括OFDMA，SC-FDE（单载波频域均衡）以及SC-FDMA程序，接收端采用经典的ZF和MMSE检测算法，程序短小精悍，相当经典，方便该领域的人学习与研究。-Single Carrier FDMA or SC-FDMA, also known as DFT-Spread-OFDM is the latest 3GPP LTE uplink transmission for a new program. 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: This book attempts to provide an overview of IP-OFDMA technology, commencing
with cellular and IP technology for the uninitiated, while endeavoring to pave
the way toward OFDMA theory and emerging technologies, such asWiMAX, LTE,
and beyond. The first half of the book ends with OFDM technology, and the second
half of the book is targeted at more advanced readers, providing research and
development-oriented outlook by introducing OFDMA and MIMO theory and endto-
end system architectures of IP- and OFDMA-based technologies.

Description: Relaying and orthogonal frequency division multiple
access (OFDMA) are the accepted technologies for emerging
wireless communications standards. The activities in many
wireless standardization bodies and forums, for example IEEE
802.16 j/m and LTE-Advanced, attest to this fact. The availability
or lack thereof of efficient radio resource management (RRM)
could make or mar the opportunities in these networks. This
paper therefore provides a comprehensive RRM algorithm for
OFDMA-based multi-cellular fixed relay networks in a way to
ensure fairness among users with minimal impact on the network
throughput (in contrast, pure opportunistic RRM techniques
always favor users with good channel conditions
