Turbo Multiuser Detection in Space-Time Trellis-Coded Systems

Turbo Multiuser Detection in Space-Time Trellis-Coded Systems

In Section 6.7 we developed an iterative receiver structure for multiuser STBC systems based on the turbo multiuser detection technique. In this section we apply the same ideas to multiuser space-time trellis-coded (STTC) systems. Moreover, by exploiting the intrinsic structures of STTC, we consider a more compact system without introducing any outer channel code.
