Space–Time Codes and their Applications in Future Communication Systems
In this thesis coding schemes for future wireless communication systems are presented:
A new class of Space-Time Codes that consists of two decoupled linear block
codes achieves a very high diversity gain in a fading environment. This codes are able
to combine this excellent diversity performance with spatial multiplexing to exploit
the high capacities of MIMO-channels.
Furthermore a new efficient intersymbol-interference cancellation method has been developed which can be used in a scalable
decoder for the new Space-Time Codes. An analysis based on extensive measurements
of Indoor Powerline channels shows high channel capacities even using very low transmitting
power to meet the German standards. So an efficient channel coding scheme
for Powerline channels is presented based on an extension of the new space-time codes
that makes it possible to achieve a high frequency diversity gain.
