Demand for capacity in wireless communication systems has been rapidly growing world-
wide. This has been driven by increasing data rate requirements of cellular mobile systems,
and demand for wireless Internet and multimedia services. As the available radio spec-
trum is limited, higher data rates can only be achieved by designing more efficient signaling
techniques.
In this thesis, we propose a new transmission scheme, which benefits from the advantages
of conventional space-time trellis codes (CSTTCs) but does not have the disadvantages,
especially for larger signal constellations. We achieve this by developing a new class of
codes, called Multilevel Space-Time Trellis Codes (IMLSTTC). The new scheme provides
a scalable and promising alternative to CSTTCs, by providing the system designer with
the flexibility to choose any desired balance between code performance, complexity and
throughput. The proposed scheme outperforms layered schemes at high SNRs, using a
smaller number of antennas.
