Abstract--We consider power control in cognitive radio networks where secondary users identify and exploit instantaneous and local spectrum opportunities without causing unacceptab...
— We analyze the performance of a wireless system that allows opportunistic spectrum sharing. The system consists of a set of primary users sharing a set of channels over a cover...
— We consider a cognitive wireless relay system that operates on secondary spectrum sharing basis using spectrum pooling. A spectrum pool comprises of a set of available narrowba...
Abstract— In this paper, we analyze DS-CDMA/OFDM spectrum sharing system based on opportunistic spectrum access (OSA). In this system, the primary network air interface is based ...
