Abstract :
In this paper, we propose a "turbo" coding scheme consisting of the serially concatenation of a channel code and OSTBC with iterative processing at the receiver. We analyze the impact of different mapping strategies on the information transfer of the space-time detector with EXIT-charts and derive some criteria for the optimum mapping strategy.
