Topics and Goals of this Course

• Main Topics
• Random Process and Noise in Frequency Domain

  Analysis
• Pulse Modulation and TDM Systems
• Text Book Communication Systems Haykin
• Other Refs Communicaiton Systems Carlson
• Communication Systems Engineering Proakis
  Salehi

  modulation, interference and nosie analysis,
  these topics will be later used in Digital
  Communication courses
• Getting basic first hand experience with some of
  the real-life issues facing an engineer working
  in a fast changing environment such as
  Telecommunications area
• Teamwork
• Change Management
• Creativity

Why do we need to do Teamwork?
If we believe we have a responsibility to make
sure our students leave MIT not only with
analytical and technical skills, but with the
so-called soft skills as well, then we have a
responsibility to provide opportunities for the
students to master those skills, especially
Teamwork.

• Our Goal To do course projects more efficiently
• Teamwork is critical in modern engineering
  environments (anywhere in the world)
• If you can function properly in a team, you can
  achieve a lot more than just doing it yourself ,
  although in the beginning it might be painful!
• Difference between Teamwork and Groupwork
• Need to Experience in order to Learn
  professional teamwork
• Process is even more important than the goal
• -gt Conference of the Birds
• A Necessary differentiating factor when
  information is available to all so easily
• Essential for coming up with creative ideas
• Will help a lot in your personal lives
• When you ask me to write a recommendation letter,
  I do not leave parts related to group work blank!!

The 7 Habits Book

• This is not just a book on personal development.
• It is used in completely professional setups at
  different universities.
• Covey, Stephen R. (1990) The Seven Habits of
  Highly Effective People, Fireside Books, Simon
  Schuster, New York, NY.
• This book is an excellent review of individual
  and interpersonal practices that will make any
  individual a more effective listener, learner,
  partner, and leader. It suggests several
  excellent frameworks to enhance personal
  performance. The chapters Be Proactive, Begin
  with the End in Mind, and Put First Things
  First are a useful way to stimulate thinking
  about a personal vision for your life and career.
  The chapter Seek First to Understand, Then be
  Understood, is the best thing Ive ever read on
  empathic listening, a critical leadership skill.
  Use this book to enhance the effectiveness of
  your learning team, and to write your strategic
  thinking paper.

• Stanford University
• Important Note Not all materials in the book are
  necessarily approved but it is a very good
  starting point

5
Role of Teams

• Teams will have regular weekly meetings and will
  work on the following subjects
• Finding creative answers to Key questions about
  course materials on a specific communication
  system
• Matlab Simulation Projects about course materials
  
• Prepare short reports on real-life devices
  (chipsets)
• Summary presentation on what you have learnt and
  used from 7-Habits and other side books

6
Some Key Questions on commercial systems

• What are the main issues in a Communication
  system?
• How can we share multiple users in a
  communication system?
• How can we send data through these systems in
  addition to voice?
• Satellite links
• Mobile networks
• ADSL
• WLAN
• Point-to-point radios

• GPS
• Ethernet LANs
• HPNA
• Homeplug
• Power Line Carrier (PLC)

7
Typical Course Simulation Projects

• Noise Generation
• Capture effects
• SNR of AM/FM systems
• Non-flat channel effects
• PLL circuits
• Synchronization issues

8
Report on Real-life Chipsets

• AM Modulation and Demodulation
• SSB/DSB Modulation and Demodulation
• FM Modulation and Demodulation
• Data Transmission over FM
• PCM systems
• E1 Systems
• ADPCM systems
• PPM Systems
• PAM Systems
• PLL Chipsets

9
Team Grading

• Teams will be evaluated by Team
  Papers/Presentations
• Students also submit individual reports on Team
  process to ensure proper teamwork

10
Output Format

• Presentation Outputs
• 3-5 power-point slides
• Make it as creative as possible
• Try to use professional humor and make it
  exciting, multimedia,
• Paper Outputs
• Similar to Presentation but with more details

11
Summary of Action Items for next week

• Get the 7-Habits book and read at least the first
  3 habits
• Review materials on Team Roles, Team Ethics,
• Have your first team meeting
• Do initial Teambuilding
• Select a team name
• Set your weekly schedule of meetings
• Set Agenda for the next meeting
• Prepare a report of your first meeting session
• Prepare a team evaluation form so that all
  members fill it out individually in next meeting
• Prepare for a review quiz on probability and
  random variables (on Monday 17/11)
• Read Haykin Introduction (p. 1-30)

12
Teamwork

• Equal and active participation Turn taking
• Say your idea
• Listen to others ideas
• Ask Questions
• Discuss and come to a consensus
• Four Rotative Roles (in addition to be part of
  the discussion)
• Facilitator (make sure the process is right,
  everybody is participating, session is going to
  the point)
• Recorder/Summarizer (make sure all important
  discussions and decisions are recorded ,
  summarizes discussions at the end and proposes
  initial action items)
• Devil's Advocate This person in this role finds
  weaknesses in the group's ideas and questions
  them and prevents the mentality where everyone
  agrees with an idea. It gives the team other
  points of view.
• Setup manager (arranges the time/location of
  meetings, prepares agenda, keeps track of items
  in the agenda, makes sure all forms are filled
  and the agenda is finished, will followup from
  previous session)
• Develop a group plan in the beginning
• How you want the group work, logistics, decision
  making, task division
• After a few sessions that team develops ,
  identify what is the main differentiating factors
  of your team and build upon them.

13
Ethics and Rules of Teamwork

• Always be on-time and be prepared
• Form an agenda in advance
• Take notes
• Make a timeline
• Have a checklist
• Teams celebrate success at milestones.
• Teams have fun.
• Teams review quality of the team process report
  problems
• Arguments should always be about ideas, nothing
  should be personal
• Decision making by consensus (all should agree
  with the decisions, do not vote)
• Teambuilding Select a topic and talk about that
  in your first session
• Problems in the university
• Movies you have seen recently
• The best advice you have received
• Best book you have read,

14
Group Evaluation Forms

• How interesting you found your team session?
• How difficult you found working in the team?
• Did you understand exactly what you should do?
• If you talked less than you wanted, why that
  happened?
• How were tasks divided between team members?
• Did you get along with everybody in the team?
• Who did most and least of talking in your team?
• Who presented the most ideas in your team?
• How well did the facilitator do the job?
• Have you had a serious conflict in your group?
  Assuming you resolved it, how did you do so?
