Key Conclusions (critical thinking):
I.OBJECTIVES
Introduction to the most commonly used antenna types and significant
design parameters
Design an antenna suitable for a 2G, 3G or 4G wireless application
deployment.
II.PARTS LIST
N/A
III. INTRODUCTION
In this lab exercise you will design an antenna suitable for a 2G, 3G or
4G wireless application deployment. Such applications include 3G
cellular (e.g. CDMA2000 evolutions), IEEE 802.11x, IEEE 802.16 and
Bluetooth. The antenna should be deployable at a cellular base station,
cellular mobile unit, Bluetooth unit, a wireless LAN access point or

2. portable unit. IEEE 802.16 base station or portable device applications
can also be implemented.
IV.PROCEDURE
A. Resources
Well known classical antenna design procedures for various antenna
types are available from Internet resources and texts such as The ARRL
Antenna Book. Consult these resources as you proceed with your design
as this will not only expedite the process but assure that your chosen
design parameters meet with FCC specifications.
Refer to the FCC Part 15 documentation and other applicable documents
to make sure your design parameters meet the FCC stipulated limits.
The parameters of primary interest include: Operating Frequency,
Directivity, Radiation Pattern, and Gain. For any application for which
you choose to design, investigate the parameters as stipulated by the
FCC. You must include these applicable parameters in your report.
B. Antenna Choice
Work with your instructor to choose an antenna to design so that the
class develops a variety of solutions. Your report must support your
choice of antenna, that is, you must give the reasons why a particular
antenna type was chosen.
For example, for a cell phone, the antenna dimension, aesthetic beauty,
and omni-directivity may be the most important factors influencing your
design choice. However, for an antenna to be deployed at a cellular
base station, features such as directivity, wide operating bandwidth and
capability to radiate signals of relatively high power may be the primary
factors around which your design is centered. As you can see, you need

3. to consider technical aspects along with practicality when designing
your antenna. The following table should help in understanding your
choice.

Title of Report:
Pulse Shaping Filters
I.We used MATLAB to designed pulse shaping filters and investigated
the filters’ Impulse Responses as key filter parameters are varied
OBJECTIVES
Use MATLAB to design pulse shaping filters.
Investigate the filters’ Impulse Responses as key filter parameters are
varied.
Observe the effect of Matched Filtering on Inter-symbol Interference
(ISI).

4. II. PARTS LIST
Equipment:
IBM PC or Compatible with Windows 2000 or Higher
Software:
MATLAB Version 7.1 or Higher
III.INTRODUCTION
Baseband signal processing is an important component of any modern
wireless system. Line Coding, Channel Coding, Encryption,
Compression and Pulse Shaping are all schemes deployed at this level.
Spectral scarcity is always a key consideration for the wireless designer.
Inter-symbol Interference and other degrading effects of a typical radio
channel are also issues that need to be addressed during system design.
In this lab we shall examine the roles of pulse shaping filters as a means
of achieving spectral efficiency and ISI mitigation. The two pulse
shaping filters we shall work with include the Gaussian and the Raised
Cosine filters.
IV.PROCEDURE
A. Applicable MATLAB Tools
Open MATLAB and familiarize yourself with the Default Layout, which
includes the Current Directory, Command History and Command
Window. You will be working primarily in the Command Window, but
the other windows may provide useful information in the future.
The Command Window is a command line environment, much like DOS
or UNIX. You will type all commands in this lab at the >> prompt.
Following each command, you will need to hit the Enter key. Also, if
you are working in the Citrix environment, there may be a lag in

5. MATLAB’s response. Some operations are VERY processor intensive
– just be patient.
To get started, type in: >>help
Scroll UP until the commcomm. Select this entry.
Scroll UP again, and look for the 3 categories that contain filter options.
List these sections, their subcategories and descriptions of each.

Introduction to OFDM Generation
I.OBJECTIVES
Introduce the student to the underlying theory of operation of
Orthogonal Frequency Division Multiplexing (OFDM).
Learn to use TIMS modules to implement an OFDM generator scheme.
Generate and analyze OFDM waveforms.

6. II. PARTS LIST
Equipment:
IBM PC or Compatible with Windows 2000 or Higher
Software:
TutorTIMS – Version 2.0 Advanced
The following TIMS modules will be required for the lab. Read about
the modules required for the particular lab section before proceeding:
Sequence Generator
Multiplier
M-Level Encoder
Phase Shifter
Master Signals
Adder
Tunable LPF
100 KHz Channel Filters
Decision Maker
III.INTRODUCTION
OFDM (Orthogonal Frequency Division Multiplexing) is a combination
of modulation and multiplexing, and more specifically, is a special case
of Frequency Division Multiplexing (FDM), as the name implies.
A single main data stream is split into many lower rate data streams
(multiplexing). Each of these streams is then individually modulated

7. onto a separate sub-carrier (modulation) and finally recombined into a
single composite OFDM signal to be transmitted.
The addition of a cyclic prefix is also an important part of OFDM,
however, this feature will be discussed but not implemented in this
introductory experiment. The coding blocks will not be covered in
detail within this experiment.
