Maximum likelihood decoding rules for STBC generalized framework for detection and derivation of accurate upperbounds

In this paper we propose the new decoding rules for STBC (space-time block codes) using the maximum likelihood (ML) principles. Using algebraic tools we are able to derive a simple matrix model which is very easy to implement in the simulation. After giving our particular detection rules, we determine a new accurate upperbound for the BER performances of STBC transmitting schemes. Simulation results are given which show the accuracy of the derived upperbound.
