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. Platform: |

Description: The major evolution of UMTS (Universal Mobile Telecommunications System) in recent years
is the High Speed Downlink Packet Access (HSDPA)which provides data rates up to 10Mbps. The
implementation of HSDPA includes multicodes transmission in joint application with Adaptive
Modulation and Coding (AMC) as well as Hybrid Automatic Repeat reQuest (HARQ).
This thesis deals with the implementation of the HSDPA simulator in FDD (Frequency Division
Duplex) mode according to 3GPP technical specifications. It also aims to study the HARQ
algorithms for HSDPA. The performance of AMC is significantly degraded when higher order
modulation (16-QAM) is used in a multipath environnement. Moreover, the HSDPA simulator requires
a very long time of computation to provide good performance in multipath channel. In order
to solve this problem, we have introduced a simplified simulator which exploits the performance
of HSDPA over gaussien channel as look-up tables to compute the block error rate in multipath
channel. Platform: |
