In this paper, a joint linear pre-coder and combiner optimization scheme is proposed to reduce the multi- user interference in the distributed antenna system (DAS). The pre-coder is designed based on the modified weighted signal-to-caused interference ratio (SCIR) which considers the interference on others caused by the desired user and the users channel condition. And the combiner is chosen based...
Block diagonalization (BD) is a famous conditional precoding algorithm in multi-input multi-output (MIMO) broadcast systems, vector perturbation (VP) and BD are combined which named as BD-VP for short and the receivers' complexity can be reduced by VP at the transmmiter. Furthermore, the performance of BD-VP in diversity is comparable because the maximum likehood (ML) method is involved. However,...
In this paper, an alternative jointly optimized transceiver scheme is proposed to reduce the multi-user interference in the distributed antenna system (DAS). First a joint design for the pre-coders and combiners is proposed based on the signal-to-leakage-plus-noise ratio (SLNR) maximization and the receive signal-to-interference-plus-noise ratio (SINR) maximization, respectively. Then a modified weighted...
In this paper, joint Haar-like feature is used for detecting faces in images. Our method is based on the co-occurrence Haar-like features which can capture the structural characteristic of the face, make it possible to construct more effective weak classifier. As the Haar-like, the joint Haar-like feature can be calculated very effective and has the robustness to addition of noise and change in illumination...
