Use of Internet:
Internet is used extensively to supplement the course material relating to wireless communication industry, products, technical tutorials, and other relevant information. Following websites will provide useful information related to wireless communications.

Computer-aided-circuit design:
PUFF software shall be used for designing the layout or artwork for the microwave circuits and the simulation results if any obtained by PUFF will be used to compare the experimental data. Additionally, MATLAB software would be utilized to understand the performance of spread spectrum communication systems.
Circuit fabrication and parts: Students are responsible for designing the circuit layout and should be familiar with circuit fabrication. Students should obtain the necessary electronic parts from the commercial vendors. The required electronic parts for each project will be specified in the lab handouts. The tools such as pliers, soldering iron, wire stripper, etc (used in the previous EET courses) are also required.
Lab hours: The wireless communication laboratory will generally be open during normal business hours on weekdays from 8 AM to 5 PM. If you cannot complete your project during the scheduled lab hours, you may work at other times, provided that no other labs are in session.
Laboratory projects :
The laboratory projects will focus on the design and development of microwave circuits for wireless communications and performance simulation of spread spectrum communications. In addition, cellular radio planning and simulation software will also be utilized. Following is a list of proposed laboratory projects and the handout on each laboratory experiment will be provided at least a week in advance.
1. Introduction to wireless communications laboratory (1 lab period)
2. Microwave filters (2 lab periods)
3. Microwave transistor oscillator circuit (3 lab periods)
4. Microwave power amplifier circuit (3 lab periods)
5. Cellular signaling, propagation, and interference using Wavetek 3600D
and SMARTSAM system (1 lab period)
6. Introduction to CELPLAN system software (1 lab period)
7. Generation of PN sequences using MATLAB (1 lab period)
8. Performance simulation of a DS spread spectrum system using MATLAB (1 lab period)
9. Performance simulation of a FH spread spectrum system using MATLAB (1 lab period)
10. Industrial visit to GTE Mobilnet (1 lab period)
Note: In addition the regular lab periods as specified above for each project, you may require additional lab hours to complete each project.
Pre-lab reports:
Your pre-lab reports consists of design calculations, schematics or circuit layouts or any other documentation specified in the lab handout. Handwritten calculations or schematics/circuit layouts may be kept in a loose-leaf binder and submitted like typical homework assignments. This pre-lab report specifies what you plan to build and is due on the first lab period of each project. After the approval of your pre-lab report, you can build and test the actual project.
Final laboratory reports:
The students are required to write an individual laboratory report (typed) for each project. MS WORD and EXCEL can be utilized for the preparation of laboratory reports. The laboratory reports are due by the specified deadline and late reports shall not be accepted, unless you justify the delay. The laboratory reports are graded on the basis of quality of presentation, completeness, spelling, grammar, format, and correctness.
Grading:
Test 1 - 20% A = 90-100
Test 2 - 20% B = 80-89
Final - 25% C = 70-79
Lab - 25% D = 60-69
Homework 10% F= Below 60
Homework: Homework will be assigned from the textbook and you are responsible for all the assigned problems. Use the office hours to get help toward homework problems. I encourage you to discuss and collaborate on homework problems, but verbatim copies will not be accepted. What you hand in should be your own work. Homeworks are due by the specified deadline and should be submitted to me in the classroom and late homeworks are not accepted. The solutions to the homework problems will be posted on the notice board.
Examinations : All the examinations are closed book and notes, unless specified. The solutions to the exams will be posted on the notice board. No makeup exams will be given unless you have an authentic reason.
Reading assignments: Read the assigned sections of each chapter before attending the lecture.
Class attendance and participation: Please attend all the classes and class participation and teamwork are strongly encouraged. Come to class ON TIME.
Academic dishonesty: Academic dishonesty is not tolerated. Cheating on exams or assignments will result in a grade of zero and referral to the Dean of students. Please read the university policy with regard to academic dishonesty in your handbook.
Laboratory report writing format:
Following is the suggested lab report writing format. The report should contain the following items (in proper sequence) as shown below:
1. Cover sheet indicating the course number, lab section, date, title of the experiment, and names as shown below.
EET 414, lab section (a) or (b) Laboratory Report Spring 2000
Title of the experiment:
Date:
Names:
1. Objectives of the experiment
2. Test equipment used (specify the model numbers and type of equipment)
3. Design calculations, layout, artwork, and simulation results
4. Circuit diagram (specify all the components and the dimensions)
5. Test procedure (write a step-by-step procedure in your own words and sentences)
6. Data/Results/Graphs (put the data or results in tabular form)
7. Discussion of results
8. Conclusion (discuss the main findings of the experiment with respect to the design objectives and expected results. If the experimental results deviate, explain the reasons for not meeting the desired results).
9. Include any references or data sheets as an appendix
General guidelines:
1. Your writing communication skills will be graded based on grammar and spelling.
2. Neatness and good presentation of the results are important.
3. Verify your design calculations with your instructor before designing a PCB layout or artwork.
4. Plan early and procure all the required components.
