What is LTE
LTE: it is the short name oflong-term evolution, marketed as 4G
LTE,
and its evolution is named after LTE-Advanced (marketed as
5G)
Main air-interface: Evolved Universal Terrestrial Radio Access
(E-UTRA)
Physical Layer technology:
Orthogonal Frequency Division
Multiple Access (OFDMA) [downlink]
Single CarrierFDMA (SC-FDMA)[uplink]
System architecture: not very far from
3G; however, we need to write down two
Important terminologies: UE: user equipmentor mobile unit
eNodeB (evolved Base-station system)

C++))) [4 topics
Project code: DSPUeE-Platform]
Axxcelera LTE Project:(needs a good theoretical back ground and
MATLAB knowledge)
o LTE-A research on co-operative multi-points (2 topics)

A basic academic ideas that evolved recently to a real
We need to build a UE Tester that is capable to debug the
eNodeB
failures and show them in Matlab
Our project is a huge university project that is handled among
5
Professors; each deals with it from his experiences and
tools
My prospective team will be mainly developing with MATLAB
and
for speed issues MATLAB/C-mex and C (not even C++; tutorials
will
be avilable)
Expected knowledge you will gain:
LTE-Advanced know how and building blocks
Research, development, and design
Real standard interface and, hopefully, contribution
Possible cooperation with a highly interested German firm
Long-term project that will encourage you to continue your
research if you liked
the topic.
Individual concrete work as well as cooperative and creative
team work
Prepares you for LTE market

What are the problems with the current LTE-UE-Testers:
LTE-Advanced features are not covered and they are not able to
be scaled up
for them
Size and weight; check the internet for the current sizes and
weights to see the
real problem ;)
Price; you are buy (when you like to buy an LTE tester) an old
technology to test
present devices with far-future prices --- a real miss!!
5GET: What do we need to developA holistic view: An AMC form
factor box with Matlab-and-DSP (our team), an air-interface
(again
our team), and FPGA function bank (with the electronics
team-members)
This box should emulate* a real UE in all its situations
You will be a developing a part of the project in 3~4 months
The 5GET Project
*: what is the difference between simulate and emulate?

Design and Research of Embedded Architectures using
MATLAB (DREAM)
The 5GET Project
Develop a MATLAB simulation environment for
LTE-A baseband for one the following:
Develop for UE in UL channel with SC-FDMA
Develop for UE in DL with OFDMA (single antenna systems
[SISO])
Develop for UE in DL with OFDMA (multiple antenna
systems[MIMO])

USRP 210n A software defined radio (SDR)
The 5GET Project
This project will allow you to build a simple base-station
(again, called an eNodeB)and a simple user terminal (called UE)
using a standard PC/Laptop and a low cost
software radio frontend (our fancy USRPs)
These are the topics (with the code USENet):
- eNodeB signal acquisition in UL with multi-user interface
- eNodeB signal generation in DL with, also, multi-user
interface- UE emulation in both UL and DL

TI C6670 Digital Signal Processor
The 5GET Project
This project will allow you to developthe LTE-Baseband outside
PC, and
rather do it on a special processor
called DSP (digital signal processor)
You will be developing in this project
using MATLAB Simulink (TI-toolbox)and C (simple C for DSP and
not C++)
The projects will be:
- UE DL for multiple antenna system
- UE DL for single antenna and TX
diversity- UE UL for single antenna system
- UE multi resource analysis and
decoding functionalities

LTE System-Level Simulator (w/ and w/o Relays)
The 5GET Project
In order to evaluate the performance of new mobile network
technologies, system
level simulations are becoming very essential. In this project,
we need to considera network with/without Relays to evaluate the
overall throughput enhancement in
the network and, particularly, at cell edges and during
hand-offs.
Thus, we need to study Network overall system performance
(throughput) with practical UEs traffic model(s)
Monitor throughput in the whole network (see the throughput
heat-map example)
Throughput, hand-off capabilities, and cell coverage
enhancements using Relays
