After successful completion of the course, students are able to distinguish between robust and optimum communication systems. The students are able to design and analyze spread-spectrum systems as representative of a robust communication system.

Motivation. Interference reduction in general: Communication environment, Orthogonality, Figure of merits, Complexity, Interference avoidance, Robustness, Reliability, Communication resources, Responsibility. Conventional binary communication system. Spread-Spectrum System. Discrimination between robust systems and systems employing interference reduction. Principles of interference combating: Decorrelation, Interference reversal. Interference reduction techniques: Whitening, Estimating, Transformation, Nonlinearity, Orthogonality. Advanced interference combating techniques: Preventive interference combating for future wireless applications, (Adaptive) nonlinear pre-processing, Cooperative and non-cooperative interference combating. Concluding considerations: Evolution of interference combating techniques, Future of interference combating techniques. Brief literature review. Spread-Spectrum technology in detail (principle, performance, synchronization, RAKE, Code-Division-Multiple-Access (CDMA), multi-carrier CDMA, multi-user detection (MUD), signal design, GPS).

The contents of the course will be presented with mathematical models and partially visualized with simulations. Relevant examples present typical results.
