Strategic
Performance
Indicators (SPIs)

SPIs are a subset of the abilities a student will be able to demonstrate upon successfully completing the course.

Outcome 1 (Students will demonstrate expertise in a subfield of study chosen from the fields of electrical engineering or computer engineering):
1.	Explain the relative merits of various modulation schemes, especially in terms of their power efficiency and bandwidth efficiency.

Outcome 2 (Students will demonstrate the ability to identify and formulate advanced problems and apply knowledge of mathematics and science to solve those problems):
1.	Demonstrate how to formulate detection strategies that optimally account for the statistics of the noise.

Outcome 3 (Students will demonstrate the ability to utilize current knowledge, technology, or techniques within their chosen subfield):
1.	Predict the performance (primarily in terms of power efficiency and bandwidth efficiency) of a newly encountered modulation scheme.
