Assignments and Projects

Assignments will determine 70% of your grade. They will be handed out every two weeks and consist of mixed problems in theory and implementation. Implementations should be done in Matlab (C,C++ is fine too). The deadline for submission is at midnight on the due date. Please submit your assignments as pdf and commented code.  Assignments can be downloaded and uploaded through CMU Blackboard.

Projects will determine 30% of your grade. The projects ideally help you with your research. Teams of up to three students are encouraged. Projects include a presentation talk during the last week of lectures and a final technical report that is due one week later.
