In this work, we consider the application of the well-known space-time block code (STBC), the Alamouti-scheme, as inner code within a “turbo” coding scheme for the multiple-input-multiple-output (MIMO) Rayleigh fading channel. We analyze therefore the applicability of the Alamouti-scheme for iterative space-time detection and decoding applied at the receiver. To this end, we use extrinsic infor...

Achieving a practical and productive balance in collaborative research between partners from high and lower income countries (North-South Collaborations) requires seeking win-win solutions. This issue requires time to engage each other and to understand each participant’s research priorities and to identify areas of mutual interest. In SACTRC’s experience, key elements include; building researc...

. We describe here our first effort for developing a virtual talking head able to engage a situated face-to-face interaction with a human partner. This paper concentrates on the low-level components of this interaction loop and the cognitive impact of the implementation of mutual attention and multimodal deixis on the communication task.
