• What do we have
– 5th Generation Embedded Tester (5GET Project – GUC
university project)
– R&D project of Axxcelera Inc. (sponsored by Axxcelera
Egypt)
– LTE system level simulations (offered for both
Communication and Network)
– RFID (not covered in these slides –offered by Eng. Abdel Fatah and my
co-supervision and Dr. Khaled El Mahgoub (Trimble Navigation Inc.))
What is LTE
• LTE: it is the short name of long-term evolution, marketed as 4G LTE,
and it’s 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 Carrier FDMA (SC-FDMA)[uplink]
• System architecture: not very far from
3G; however, we need to write down two
Important terminologies:
– UE: user equipment –or mobile unit
– eNodeB (evolved Base-station system)

• 5GET Project: o LTE-A link-level design and simulation using MATLAB
o [3 different topics Project code: DREAM]
o LTE-A Air interface using USRP 210 (this fancy kit which needs only
MATLAB experience) o [3 different topics Project code: USENet]
o LTE-A implementation using TI DSP C6670 (the strongest ever for LTE
development; we have 8 kits! o It needs matlab and programing skills (Java or even less, C (not 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)
o LTE-A research on multiuser systems (2 topics)
• Resource allocation (a network level-simulator):
o LTE system level simulator (1 thesis) (Offered for network and comm.)

• 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
The 5GET Project

• 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 develop –A 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
9
TI – C6670 –Digital Signal Processor
The 5GET Project
This project will allow you to develop
the 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 consider
a 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
