Mobility support for the next generation IPv6 networks has been one of the recent research issues due to the growing demand for wireless services over internet.
In this paper,we suggest an adaptive watermarking method to improve both transparence and robustness of quantization index modulation(QIM) scheme. Instead of a
In this paper,we propose a new linear multiuser receiver for synchronous code-division multiple-access (CDMA) systems,referred to as the orthogonal multiuser(OM
Aiming at the problem of resource allocation in multiuser multi-input multi-output (MIMO)systems,a new power allocation algorithm based on dual waterfilling is
We propose a procedure to forecast short time series with stable seasonal pattern.This new method is motivated by the observations that short time series arise
Wireless mesh network is a new emerging field with its potential applications in extremely unpredictable and dynamic environments.However,it is particularly vul
This paper,resents a system called Athlos2,which implements strong access control for athletic events, enhancing the safety feeling of event spectators. Athlos2
In this paper,some issues concerning the Chinese remaindering representation are discussed.A new converting method is described. An efficient refinement of the
