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 or significant higher
capacity based on spacial multiplexing. In this contribution
we will point out the excellent possibilities of SC/FDE to be
combined with diversity techniques, as the process of the
equalization itself can be combined with receive diversity as
well as with space time block (STBC) decoding. This
combination gives a reduced signal processing complexity as
well as the expected enormous performance gain. Especially
the concept of STBC allows an advantageous combination
with SC/FDE as both are based on a blockwise processing
that can be formulated advantageously in the frequency
domain. Our simulation results are based on the parameters
of the IEEE 802.11a standard.
