The student should recognize that interference combating in wireless applications is a valuable resource to increase the capacity. This capacity resource is not fully exploited nowadays. Learn to analyze the methods of interference combating. The student should be able to distinguish between optimum systems, robust systems and systems employing interference reduction techniques. The student should be familiar with the most popular interference reduction schemes. Recognizing that the Spread-Spectrum technology is a member of robust technologies.
