ENSC 428 – Digital Communications Semester 2008-1 Project Outlines as of Jan. 7, 2008 1. Purpose To train students to simulate communication systems and to gain intuition about the systems. To learn to use MATLAB and Simulink. 2. Objectives The goal of this project is to create a Simulink model of digital communication systems. The communication system should include at least the modulator, the demodulator, and the channel models in the figure above. The channel model must include noise. You are encouraged to play with wireless channel models (Proakis Ch. 10). Commensurate to your talents and interests, adding more modules in the system is encouraged for your

project e.g., direct-sequence spread spectrum (Proakis section 10.3), carrier synchronization module, symbol synchronization module, etc. After constructing a Simulink model, you should run simulation and report the bit error probability. You must then observe how bit error probability changes as you change

Unformatted text preview: system parameters. System parameters can be the channel parameters (e.g., the delay spread, Doppler spread, etc.), constellation size (the value of M in MQAM), noise power, channel coding scheme, etc. For those who are unfamiliar with Simulink, I encourage you to start playing with Simulink early so that the experience may be fun rather than pain. 3. Organization You can either team up with another class mate (a group of two people) or work alone. Each unit (a group of two or a singleton) must submit a report along with electronic version of the created Simulink model. Upon completion, each unit needs to schedule 30 minute interview with the instructor and to demo the simulation, no later than April 1, 2008. The report and software in electronic copy must be submitted prior to the interview. Thus, April 1, 2008 is the project deadline. 4. Expectations and Grading The completed Simulink model must be able to successfully simulate the system....

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
