Multimode precoded MIMO-based qualitative video streaming using frame type information

In this paper, we utilize the knowledge of frame type and structure combined with multimode precoded MIMO transmission scheme for video stream, in order to achieve a better tradeoff of physicl layer performance (eg., SER) and the transmission delay via a proposed two-stage selection algorithms. The algorithm adaptively selects the optimal transmission mode (DIV or MUX) and the corresponding precoder according to the channel state information (CSI) and a simplified queue state information (QSI) which refers to the information of frame type and structure. The proposed algorithm doesn´t cause the additional cost and complexity and provides a potentional performance on the transmission delay, which is illustrated by numerical simulations.
