This course introduces fundamental technologies for wireless communications. We will address the following topics:
In the course, students are expected to gain some hand-on experience on W-CDMA systems (3G wireless systems).

Tuesday, periods 8-9 (3:00 pm-4:55 pm) & Thursday, period 9 (4:05 pm-4:55 pm)
(Note room change from LAR 310)
The course consists of 28 lectures, 6 homework assignments, 1 project, and 2 exams.
This course is primarily a lecture course. I cover all important material in lectures. Since EEL 5544 is a prerequisite, 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.
The class project is described here.

All students admitted to the University of Florida have signed a statement of academic honesty committing them to be honest in all academic work and understanding that failure to comply with this commitment will result in disciplinary action. This statement is a reminder to uphold your obligation as a student at the University of Florida, and to be honest in all work submitted and exams taken in this class and all others. Refer to the academic honor code for more information.
Students are encouraged to discuss class material in order to better understand concepts. All homework answers must be the author's own work. However, students are encouraged to discuss homework to promote better understanding. What this means in practice is that students are welcome to discuss problems and solution approaches, and in fact can communally work solutions at a board. However, the material handed in must be prepared starting with a clean sheet of paper (and the author's recollection of any solution session), but not refer to any written notes or existing code from other students during the writing of the solution. In other words, writing the homework report shall be an exercise in demonstrating the student understands the materials on his/her own, whether or not help was provided in attaining that understanding.

|Midterm Exam||30%||March 15|
|Final exam||30%||April 27|
|Project proposal||5%||March 17|
|Project report||15%||April 26|
The class project will be done in a group of at most four members (that is, 1 or 2 or 3 or 4 members are allowed). Each project requires a proposal and a final report. The final report is expected to be in the format of a conference paper. On March 17, the project proposal (up to 2 pages) is due. On April 26, the final report (up to 10 pages) is due. For details about the project, please read here.
Suggested topics for projects are listed here.
