Course Description

- This course teaches the fundamentals of digital communication that are the foundation for many of the techniques employed in spread spectrum communications.
- These include spreading sequence, direct sequence (DS) and frequency hopping (FH) spread spectrum, performance of spread-spectrum systems in jamming environments and capacity calculation for CDMA systems.
- Students gain an overview of wireless architecture, spread spectrum systems, code synchronization, design of optimum receivers, CDMA theories, calculation of theoretical capacity of CDMA system, effects of interference in CDMA, and 3G wireless systems using CDMA technologies.

Project

- The course project is an individual simulation study of systems and algorithms related to the material presented in class.
- You can conduct your simulation study based on one (or more) of the papers in the list below.
- Alternatively you can select your own reference papers, provided that we mutually agree on the selection.
- You have to understand the material in the paper and write your own MATLAB (or C, C++, Fortran, etc) programs to implement and test the algorithms described in the paper.

- Create your own test scenarios, don't just repeat what are done in the paper.
- Feel free to modifiy, improve, or extend the original alogrithms and scenarios described in the paper.
- A ground-breaking research topic is excellent, but not needed. However, you are expected to show a substantial effort in your project.

- Goal done in the paper.
- I believe the best way to learn a subject is by working on a project.
- First, you have to select a topic. In the process, you have to review the class material. You have to learn how to search and select useful information from research papers.
- The next step is to develop your ideas and work them out. This step helps you to review, consolidate, and practice the knowledge you learn in class.
- The final step is to write a report on your findings. To do so, you need to organize your ideas and results in a clear and logical manner so that they can be understood by the readers of your report.
- I believe a well-written report is as important as a good idea. There is no point in doing research if no other person can understand and use the result.
