Abstract

In this paper, we will present and evaluate a new detection algorithm for decoding multi-group space time trellis coded systems. These systems consider a single user who transmits simultaneously through K parallel space time trellis encoders. Therefore, they can provide high spectral efficiencies similar to the BLAST architecture plus transmit diversity advantages and coding gains. The developed detector is called maximum a posteriori spatial sequence estimator and it has the flexibility of trading complexity with diversity advantage. The algorithm could provide higher receive diversity with higher complexity. The simulation result shows a performance improvement of this new algorithm over interference nulling and cancellation techniques.
