Hierarchical DWT Based Optimal Diversity Power Allocation for Video Transmission in MIMO Wireless Systems With Quantized Feedback

In this paper, the authors propose novel algorithms for singular mode diversity order based optimal power allocation for video transmission in Multiple-Input Multiple-Output (MIMO) wireless systems. They motivate a Discrete Wavelet Transform (DWT) and Hierarchical Block Motion estimation Algorithm (HBMA) based spatio-temporal video decomposition that is naturally suited to the ordering and diversity properties of the MIMO channel singular modes for video layer allocation. Based on this paradigm, they propose a framework for the MIMO Singular Value Decomposition (SVD) based optimal power allocation, specifically for the context of MIMO video transmission.
