Original Kurzfassung:
In this work we investigate the possibilities of combining diversity techniques with a Single
Carrier System with Frequency Domain Equalization (SC/FDE), as future transmission concepts will also
be judged by their possibilities to be combined with multiple antennas. Concepts of multiple antennas
allow either a significant performance gain through diversity (and) or significant higher capacity based on
spatial multiplexing. While it is topic of many contributions to improve the concepts of antenna diversity
itself, it is topic of this paper to point out the advantages when combining SC/FDE with diversity
techniques. It will be demonstrated that SC/FDE shows excellent possibilities to be combined with
diversity techniques, as the process of equalization itself can be combined with receive diversity as well
as with space time block (STBC) decoding, that can be carried out advantageously in the frequency
domain. Besides that an overall system approach will be discussed that includes aspects of
implementation, equalization, modulation and coding.
