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: OnPerformanceLimitsofDFTSpreadOFDMSystems
DFT Spread OFDM has been proposed recently to
reduce the Peak to Average Power Ratio (PAPR) of conventional
OFDM transmission. Besides PAPR reduction, an important
implication of DFT Spreading is that the independent parallel
sub-channels between the sub-carriers cease to exist. This in
turn leads to difference in its performance limits as compared to
the conventional OFDM system. This paper analyzes the error
probabilities of DFT Spread OFDM systems, and derives their
analytical closed form expressions for the AWGN, fading AWGN,
multipath and fading multipath channel scenarios. Simulation
results presented in last section confirm the validity of the derived
analytical expressions.
