The use of indoor wireless communication systems is continuously increasing while the main concern is how to provide nonstop high quality service. This requires positioning the base stations in a way that optimise the quality measures such as the path loss in addition to minimising the transmitted power in order to reduce the power consumption as well as the interference with neighbour base stations...
In this paper we consider the problem of detecting of primary users (PU) including transmitter and receiver in cognitive radio (CR) networks. In ordinary situation, it is difficult to detect whether the primary receiver exists even where the receiver is. In this work we propose a novel system design combined with CR mobile station and base station to cooperatively detect the location of primary transmitter...
