: Unit nonresponse and item nonresponse in sample surveys are a typical problem of nonresponse which can be handled by weighting adjustment and imputation methods, respectively. Th...
In a frequency selective slow-fading channel in a MIMO system, the channel matrix is of the form of a block matrix. This paper proposes a method to calculate the limit of the eige...
The instability of the tree-like multicast overlay caused by nodes' abrupt departures is considered as one of the major problems for peer-to-peer (P2P) multicast systems. In ...
