Kurzfassung
Regarding the ever-growing demand for mobile communications it is necessary to consider different approaches for increasing spectral efficiency, since spectral resources for wireless applications are limited. In this paper, we focus on OFDM (Orthogonal Frequency-Division Multiplex) based overlay systems, which share a frequency band with already existing systems without degrading their performance. An emphasis is put on three overlay scenarios in different frequency ranges which serve as realistic examples for the challenges for OFDM based overlay techniques. These three scenarios show that overlay systems are a promising approach for enhancing spectral efficiency by implementing additional systems in existing frequency bands.
