Small cell networks are considered one of the key technologies in the next generation wireless networks. One of the main challenges in this area of research is how to tackle the problems of interference and resource allocation, especially for the hyper dense deployment of small cells. In this paper, we study the problem of cooperative interference mitigation in a small cell network. In particular,...
Vectoring is a well-known technique to mitigate multi- user interference in the downlink Digital Subscriber Line (DSL) transmission. While effective in canceling interference, vectoring does incur major computational overhead, resulting in significant energy consumption when the number of lines is large. To facilitate energy efficient transmission, a mechanism called discontinuous operation (DO) has...
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...
