Abstract: In this paper, we will propose and evaluate the
performance of several decoding algorithms for multi-group
space time trellis coded (MGSTTC) systems. By considering a
single user who transmits simultaneously through K parallel
space time trellis encoders, the system can provide high spectral
efficiencies; transmit diversity advantages and coding gains. The
system is analogous to synchronous multi-users each is
transmitting a space time trellis code. The transmitter will divide
the information stream and transmits from each encoder (called
a group) simultaneously resulting in an increase in the
transmitted data rates. The receiver will apply some multi-user
detection (MUD) algorithms to detect and decode each group.
The paper will focus on joint detection and interference nulling/
