RYERSON UNIVERSITY
Department of Electrical and Computer Engineering
ELE745 – Digital Communications - Fall 2011
Course Information 

This course covers basic principles and techniques of digital communication systems. Lecture topics include: analog to digital covertion via sampling and quantization; baseband transmission; different line codes, pulse shaping and power spectral density, intersymbol interference, matched filter detection Gaussian channels, digital carrier modulation, coherent and non-coherent detections and bit error rate estimation for various modulation schemes. Laboratory work is based on Matlab software.

NOTES:

·         Assignments: There will be some assignment problems for each chapter. The assignment will not be collected. However, students are expected to solve all assignment problems. Information about these assignments will be posted on the course homepage.

·         Middle Term Exam: 2-hour closed-book exam, scheduled on Friday, Oct. 21, 2011, 2-4 PM, .

·         Final Exam: 3-hour closed-book exam.

·         In-class quizzes: pop-quiz, no announcement.

·         Lab report: Matlab Experiments (Laboratory hours are flexible and lab reports are required). A lab report shall generally include at least the following: the prelab solutions, experimental methods and procedures, experimental results (including figures), answer questions (if any) in lab materials, explanation of the results, conclusions and discussions. You should also include your matlab codes in the report.

·         Department policy: In order to achieve a passing grade in the course, the student must pass both the theoretical and the laboratory components.

·         Lab hours are flexible. You may do your lab whatever time you like, but the lab facilities (ENG 408) are reserved for ELE745 in the time slots shown in your timetable. Please note the TAs are available to answer your lab questions in the office hours or any other time by appointments.

·         All labs are matlab experiments. The ELE745 toolbox is necessary to complete the lab. It can be found in directory /usr/common/matlab/toolbox/ele745. If you copy it to you local computer, be sure to add it to your matlab path. Labs begins from the week of Sep. 13.
