  1. EE320 Telecommunications Engineering Study Plan James K Beard, Ph.D. jkbeard@temple.edu http://astro.temple.edu/~jkbeard/

  2. Topics • Essentials – Text, SystemView, etc. • Course Objectives, Summary, and Content • Study Plan • Scope and coverage • Feedback and consultation • Study problems overview • Term Project • Suggested problems and examples • By chapter of the text • Simple – not marked, usually 15 minutes more if you really need to work them • Intermediate – marked as difficult or advanced • In-depth – for the interested, after you master the basics Study Plan

  3. Essentials • Text • SystemView • Prerequisites • Analog and Digital Communication: EE300 • Analog and Digital Communication Laboratory: EE301 • SystemView • Office • E&A 709 • Hours MWF 10:30 AM to 11:30 AM • Tuesdays 3:15 PM to 4:30 PM Study Plan

  4. Text and TUARC • Text • Simon Haykin and Michael Moher, Modern Wireles Communicatinons ISBN 0-13-022472-3 • SystemView User's Manual, Elanix, Inc • http://www.elanix.com/ • http://www.elanix.com/pdf/SVUGuide.pdf • Look at TUARC • K3TU, websites • http://www.temple.edu/ece/tuarc.htm • http://www.temple.edu/k3tu • On roof of E&A building • See Dr. Silage for access Study Plan

  5. Obtaining the Text • Price is $111.15 new • Available from (see links on home page) • Barnes & Noble • Amazon • Op Amp Books • Used prices are $45 to $75 • Shipping is same-day or next-day • Do order the text • From someone who lets you know when you will receive the book • From someone who has the book • Do not order the text • From anyone who defers shipping – they don’t stock it or worse • From anyone that isn’t in the retail book business Study Plan

  6. Ordering Books • Order only for immediate shipment • Delayed shipment means that they don’t have it • If they offer a discount, they won’t get it until they can find it for less • You can get it as cheap as they can • Amazon, B&N, et al offer used books Study Plan

  7. Course Objectives • Objectives as audited by ABET accreditation agency • Identify • Concepts of pass band coherent and non-coherent modulation systems • Societal and global issues in communication regulatory affairs • Apply Principles • Angle modulation and demodulation to send and receive information • Random processes to analyze the source and magnitude of error in information reception • Signal analysis to optimal and efficient modulation systems • Information theory to improve the performance of digital communication systems • See Temple course web site for more information • http://www.temple.edu/ece/ee320.htm Study Plan

  8. Course Summary • Thirteen weeks of classes • Two in-progress exams, one final exam • Open book • Practice exam prior to first exam • In-progress on 5th and 9th weeks, 20% of grade • Take-home supplementary exam • Final on fifteenth week, 40% of grade • Individually assigned project • Assigned in fifth week • Execute your project in SystemView • 40% of grade • Deductions from final grade • 0.5% for each unexcused absence • 1% for each missed 10 minute Pop Quiz response Study Plan

  9. Course Content • EE320 is audited by ABET • Content is defined as part of curriculum • Course as formulated here is part of Temple’s accreditation agreement with ABET • Content is selection of subjects from text • Selection is based on omitting overlap with EE300 • Topics included are selected to support curriculum • EE320 is part of a degree program • Material builds on prerequisites • Material supports follow-on courses Study Plan

  10. The Term Project • Continue with the start that you turned in with the first quiz backup • Input • Frequency sweep 1000 Hz to 3500 Hz • Noise to obtain 20 dB SNR • Sampling to obtain good performance • Do NOT pitch your beginning and pick up the ADC to bitstream modules as a template • Sample and encode/decode as instructed • Measure BER vs. Eb/N0 as instructed • Compare hard decoding with soft decoding Study Plan

  11. Topics (1 of 2) • Propagation and Noise • Modulation • FDMA • Pulse shading, power spectra, and FDMA • Bit Error Rate • Coding • Information theory, and convolutional codes • Maximum likelihood decoding • Noise performance • TDMA Study Plan

  12. Topics (2 of 2) • Spread spectrum • CDMA • Direct-sequence modulation • Spreading codes and orthogonal spreading factors • Gold codes • Code synchronization • Power control • Frequency hopping and spread spectrum • Wireless architectures Study Plan

  13. Other Topics • Examples • Antennas • Some elements in Chapter 2 • Basic principles of antenna gain are given • Supports the link budget equations • Spacecraft constellation design – Out of scope of the course • Limitations and prerogatives • EE320 has a lot of topics for 13 weeks – time is tight • Some controlled digression or exposition for context or to supplement the text material is good • Time spent on unplanned material must not push planned topics out of the course Study Plan

  14. Scope of the Study Plan • Suggested extra readings • Scope of the topics • Homework problems • Selected for their study value • Chosen to take about 15 minutes apiece • From the Text • Three to five per chapter • Suggested examples from the text Study Plan

  15. Coverage of the Study Plan • Text, Chapters 1 through 3 • More will be added as they are needed • Extra topics are available • SystemView examples • Modulation/demodulation Study Plan

  16. Feedback and Consultation • Let me know by email whenever you • Are behind in the reading • Have a problem with a study item • Specific issues, please • Good: “I don’t understand Problem 2.1 p. 18” • Good: “I need a little explanation of Example 2.17 pp. 75-76” • Bad: “I don’t understand Chapter 1” • Channels • Email • Simple, one-time issues such as Good above • Anything that is between you and I • Office – Topics that require a conversation, not a single answer or response • Phone – during office hours only; email or visit preferred Study Plan

  17. Study Problems Overview • Several are given for each chapter • Pick the easiest first • Some of the longer or more difficult problems are marked as such here – don’t do them first • If you have difficulty with a problem and can’t resolve your problems with the text, put it aside and come back to it later • In the event of difficulty • If an example is given, go through it thoroughly first • Re-read the text sections relating to the problems • Put it aside and come back to it after you work others • If the difficulty persists, send me an email • Emails to the Professor • Give the problem number • State your difficulty as specifically as possible Study Plan
