This course introduces fundamental technologies for wireless communications. This course is primarily a lecture course. I cover all important material in lectures. I assume some previous knowledge about probability theory and stochastic processes, and hence I will cover some material very quickly. Thus, depending on what and how much you recall from earlier study, varying amounts of reading in introductory books on probability theory and stochastic processes (other than the course textbook) may be necessary; these readings are up to the student. I will only give reading assignments from the course textbook.
Some problems in the exams will be similar to those in the homework. As long as you work out the homework by yourself, you will be successful in the exams. The problems in the exams are designed to prevent the students from memorizing the homework solutions without understanding the fundamental principles, concepts, and theories. So, to prepare the exams, the first thing is to understand the material; then use the homework problems to test your understanding.
Course Objectives:
1- Upon the completion of the course, the student should be able to
- 2- distinguish the major cellular communication standards (1G/2G/3G systems)
- 3- characterize the tradeoffs among frequency reuse, signal-to-interference ratio, capacity, and spectral efficiency
- 4- characterize large-scale path loss and shadowing
- 5- characterize small-scale fading in terms of Doppler spectrum, coherence time, power delay profile, and coherence bandwidth
- 6- analyze the error probabilities for common modulation schemes analyze the performance of trunked radio systems
- 7- describe different types of diversity and how they improve performance for mobile radio channels
- describe simple equalization schemes characterize TDMA, FDMA and CDMA.
Class Project:
The class project is done in a group of at most four members. Each project requires a proposal and a final report. The final report is expected to be in the format of a conference paper the project proposal (up to 2 pages) is due.
Homework:
- There are six assignments. Due dates of assignments are specified.
- No late submissions are allowed. The lowest homework grade will be dropped. Solutions provided by the instructor will be handed out in the next class after the homework is due.
- If you wish to dispute a homework grade, you must return the assignment along with a succinct written argument within one week after the graded materials have been returned to the class. Simple arithmetic errors in adding up grade totals are an exception, and can normally be handled verbally on-the-spot during office hours of the TA. For all other disputes, the entire homework may be (non-maliciously) re-graded, which may result in increase or decrease of points.
